355

[Cruze_JosephM]

Well guys this is what I plan on going with

http://www.summitracing.com/parts/fem-csmhp766-311/overview/make/chevrolet

What would be the best cam for a 355 I mean I'm not looking for nothing special really

[Cruze_JosephM]

I went and got that lt1 block from Kansas I will post pictures here in a bit

[Cruze_JosephM]

Can I use stock heads with a 355 or will I need to get them machined and what about the intake as well I need as much information as I can get I have been doing A LOT of research on these motors and it is hard to find anything since I am using a lt1

[KWBaraka]

Can I use stock heads with a 355 or will I need to get them machined and what about the intake.....

A 355ci is just a 350 with the cylinders bored from 4" (stock) to 4.030".

You can use stock EVERYTHING if you want.....or you can go high-performance. That's all up to you and your wallet.

The only question is......has your block been bored to 4.030". If so, that kit is good-to-go!!!!

Best of luck!

[Cruze_JosephM]

So I can use everything just bore my motor over also what cam should I get plus springs lifters and rockers? I mean I want the HP but also a daily you know

[Catmaigne]

Personally, I wouldn't bother changing out the pistons for a mild DD rebuild. Do you plan on spraying? Those forged Speed Pros are going to be heavy and won't be a step up over hypers NA.

And the CC503 is a great DD cam on stock heads (ported or untouched) if you have GEARS GEARS GEARS.

[Catmaigne]

Don't be afraid to buy a used cam.

[Cruze_JosephM]

I do plan on spraying a little but not much maybe 150 shot so what cam do you think I should get in all reality because the block goes to the machine shop in 2 weeks lol

[meissen]

If you're going to be looking at buying springs, rockers, etc... IMHO just buy a package from Advanced Inductions. Give them a call and tell them what you want for drivability and they'll tailor a package to you. If I could do my LT1 build all over again I would have gone that route. The cam that AI has which is comparable specs of the CC503 just plain performs better. Plus I think the package would have been cheaper than trying to put something together your self through Summit for the CC503 cam.

[Cruze_JosephM]

Their kit at AI cost more then the rebuild kit for the 355 lmao

[RamAir95TA]

And you get so much more.

[popo8]

Their kit at AI cost more then the rebuild kit for the 355 lmao

it is... but its one of those "u get what u pay for..." things.

u know u wanna hit it with 150 shot...thats cool. but honestly..what kinda numbers do u wanna see off the bottle?

either HP or ET?

As said, that summit kit is way cheaper because that's just it. It's cheaper. That kit doesn't include rods, and it also has a HV oil pump, which unless your planning on upgrading to a bigger oil pan it may cause problems in the future.

Do you have just a bare block? Or did you buy it with the stock rotating assembly?
Is it already bored .030 over? If not and the cylinders are in good condition, there is really no reason to go the extra .030 per cyl.

There are guys that are spraying 200 shots on a stock bottom end at the track. A well set up stock bottom end with ARP rod bolts and main studs will do the job just fine.

On the valvetrain discussion, talk to AI or LE. Hands down the most logical way of getting what YOU want for a good price. Asking people what specific cam you should get on a forum is going to get your tons of different opinions and only make deciding what you want even harder. Talk to the experts like AI and LE, and you'll be happy with the results no doubt.

Really though. What do you want to do with the car? What are your goals/plans? Street car that will see a couple track days a year?

[meissen]

Their kit at AI cost more then the rebuild kit for the 355 lmao

Eh? How are you comparing the price of a bottom end rebuild kit to a cam package? Or does AI offer a rebuild kit too now? GM blocks their site so I can't view their site when I'm at work, but what I was talking about is their cam packages. If you piece together a cam package off of Summit buying the rockers, springs, pushrods, lockers, etc then you'll more than likely end up spending more than if you just buy a cam package from Advanced Inductions or LE and the difference is that with AI or LE you'll get exactly what you want. Plus the cam that AI makes which is comparable in spec to the CC503 performs better than the CC503 does.

Also agree on all points with FormulaJoe, especially the HV oil pump... surprised they would include that in the package as that's practically useless since most people aren't buying the bigger oil pans just because they did a rebuild.

[Cruze_JosephM]

It is the block with the crank cam pistons and rods that is it and it will be bored over in the next week or two to the 355 specs

[Cruze_JosephM]

And I want it to maybe run a mid or low 12 and also be a street car hell maybe a high 11 would be nice with nitrous

[RamAir95TA]

A rebuild will not give you horsepower so your expectations might be a little off...you need to change your valvetrain.

[popo8]

Hes right...if u want MORE power u have to do more than a .05 over rebuild.

Now camaroracing12 pulled off an 11.99 on a cold ass day...with just bolt ons...and no spray...so u could prob spray ur way to 12s.... but its only that fast.... on the bottle...when its off or empty ur back to a 13-14et

My factory [350] bores and pistons checked out so I basically just got new rings and bearings with better ARP rod bolts and it saved me alot of money. I recommended at least checking that route. The money I saved on NOT going .030 over and having to purchase pistons was used to buy better [GTP] heads in conjunction with a Comp XE503 camshaft, which yielded more power for the cost. The motor in a C4 Corvette moves out pretty good, gets excellent mileage, and didn't break the bank.

Saw someone saying "gears" for the XE503 and I've used that camshaft in two 3.42 geared cars without any low RPM problems. With a little stall in most autos it should be fine as well. Mail order tunes on both.

[casey20000007]

I'm tying to talk him into just doing a 383, he'll have room for more HP in the future and save time and headache in the future, Matt you need to do the bottom end like your expecting to run low numbers in the 1/4 that way all you have to do is change the top end in the future, I can help u get similar stuff like what I have or we can go a completely different rout it up to you

[Cruze_JosephM]

188681886918870Well here is the motor................Well block with some things still in it lol

[Bersaglieri]

I don't see any extra holes, check the specs, buy only what you need, use the rest for performance.

[NoMoneyZ]

I think you need to recheck your plan. Some bolt on cars hit 12's all day and cam only cars can hit 11's. Spray it and it's in the bag. An overbore is not needed if the block checks out. A solid top end will do wonders.

[Cruze_JosephM]

So what would be the best thing for the street really I'm open for ideas

[casey20000007]

I'm tellin ya man your gonna want more weather its now or later, build a fully forged bottom end if you can, go ahead and stroke it, it will leave room for horse power, you can run a 383 on stock heads with no problems I've seen 383's get 20 mpg if driven right

I need to know what cam I need for the 355 plus rockers, lifters, push rods all that I know I can user stock heads and intake I mean what else do I need just trying to make a good build

Okay guys game changer 383 it is but I will probably make my other lt1 a 355 might as well lol

[Jloshotz]

[Cruze_JosephM]

Screw it get forged internals and shoot it lol I CANT WAIT!!!!!!!!!!!!!!!!!! :D

Take lots of pics to document your build as you go, going to be awesome!

[Cruze_JosephM]

I maybe building it not sure or I may take it to someone that builds lt motors I found a guy out here in Oklahoma that knows his stuff I am going to see if he is on the forums

[RamAir95TA]

Just please do some homework first. Find successful 383 builds and emulate them. Far too often have we been seeing poorly done 383 builds lately.

Matt,

In that case....you may want to just do a budget, 350ci rebuild.

Have a shop verify that all hard parts in that block or solid, replace piston rings and all bearings, install new oil pump and timing chain.....install and go!

No particular benefit in going with a 355ci.....unless the cylinders are scarred or 'out-of-round'.....and require being bored to be made 'right'.

Best of luck!!

There is no way you can build a quality 383 for $1500, period.

I agree with the above. A stock rebuild is in your price range.

[96lt1m6]

Steel crank 550.00-1200.00
Steel rods 400.00-1200.00
Forged pistons 580.00-800.00
HD bearings 80.00-130.00
Machine block 350.00-1100.00
+ a ton more parts that will cost atleast an additional 1500.00

Yeah you wont be doing a quality durable build for 1500.00 you can do a basic 6" rod forged piston 355" for 1500.00 but the problem is you have no money left for heads and a cam...

I think you just need to do a heads and cam then get it tuned. If you do a budget 383 it most likely will not stand up to huge power later down the road. Especially with cast parts.

[Cruze_JosephM]

Cast is good up to 150 shot I am ordering the 383 kit through hawks third gen I mean I'm using this car as a daily pretty much I'm not looking for much just something that will get and go y'all know

[firebird_1995]

Is that kit already balanced? 200 for machine work sounds low. Boring a block is usually $180 alone.

[GreenZ96]

I wouldn't buy from Hawks unless you like spending a lot more or your hard earned money than you need to. Expect to pay a premium price for run of the mill parts buying there.

[RamAir95TA]

STOP what you're doing right now and take the advice us experienced guys are telling you. Your plan is a proven recipe for disaster.

Again, STOP what you're doing. Heed the advice I posted earlier about researching what WORKS and what DOESN'T. Nothing you posted is worth putting in ANY engine.

[Bersaglieri]

Junk cast cranks you find in these rebuild kits are known for SNAPPING, needed lots of work to get right, or lots of weight to get balanced. The stock crank can hold a 150 shot, but I would never spray on a cast aftermarket crank. Steel isn't what it used to be, it's all being outsourced. THE FACTORY CRANK IS BETTER. Listen to RamAir95TA and everyone else who says DO NOT get the cheap stroker kit. Refresh your factory stuff and have a faster car for the money. A 383 is only worth it if you can get the heads to hang, otherwise the 355 will be faster for the money.

[Cruze_JosephM]

What all would be the best way for a 355? I don't want mixed answers please just what would be the best route for the 355 if I can get the information for that motor build I will do that instead and listen lol

man, just save up and build your bottom end correctly the first time! it may seem like a great way to do it now with the price, but in a year when you get the bug for more power and snap a cast crank possibly catastrophically nuking the engine, you will end up spending even more in the long run! if you decide to go with a 355 then yes, you can get away with the stock crank for a while, and if going bigger.....i would NEVER put a cast part in my engine.

remember;

CHEAP
FAST
RELIABLE

pick only two.

Check what you have, use new rings and bearings, use the extra money for the cam/heads/rockers/springs. Hot 350 vs junk 383.

I have cars with both a 383 LT1 and 350 LT1 and I, ME, MYSELF, picked out the parts and BUILT BOTH. I'm not giving you advice without experience.


Give us a budget.

[96lt1m6]

Generally, as threads from 1997 to present date are,"just got my new 383 done and I have 1300 miles on it and it has a definite vibration and a slight sound coming from the motor" yeah that sound is the BROKEN cast crank ya got a smoking deal on!!!!!!!
The factory Lt1 crank is one of the most durable canoe I have ever put my hands on from a stock car WHY would one put a less quality crank into a motor for a few extra cubic inches??????????????????? Makes no damn sense!

He mainly wants the torque guys not looking for power at the moment, he's gonna make his other lt1 a power motor


SMOKE TIRES NOT DRUGS

[firebird_1995]

I always thought the lt1 from the factory had great torque output and range. Comes in quick and stays there. If I were going to do a best bang for the buck rebuild that would hold up I would,
Disassemble the engine.
Take it to the machine shop.
Have them check the bore. If good, hone.
Have them check the crank. If good, polish.
Install ARP rod bolts and recondition the rods.
Install ARP main studs and line hone the block.
Install cam bearings.


At this point you would have them spec out your bearings and rings. You could install them yourself and save some money. Chances are they would assemble it for around $200. I would estimate it would take about $800-1k to do the whole short block.
If you have the scratch, a head and cam kit combo is $1500 from le. The heads come with springs so all you would need is gaskets and roller rockers. Figure another $500.
Timing chain, upgraded fuel injectors, fuel pump, another $500.
Probably gonna want some headers and exhaust, another $500
Depending on the head/cam combo this would net you around 500 hp at the crank for $4000 (still not tuned though).


Now if you want to spray it to 500 at the crank, id do the bottom end the same way, keep the stock heads, pick up a used cc503, springs and roller rockers off the board and let it eat

[RamAir95TA]

If he thinks a 383 on stock heads and cam is going to have loads of torque he's horribly mistaken.

He's looking for around 320-350 HP and bout 475-500 torque if possible

Those are some pretty ludicrous goals. It's just not going to happen. The stock rebuilt 350 is all he's got the budget for.

[casey20000007]

What would the numbers be around if he did build the 383 and use stock ported heads with a cc503


SMOKE TIRES NOT DRUGS

[RamAir95TA]

Maybe 330-340whp, about the same torque, maybe more, but it will be an absolute dog with the stock heads.

Don't let your friend half-ass this build. He's going to spend FAR more $ in the long run. Save the $ to do it right and do it once. Take my word for it. Doing it twice BLOWS.

[casey20000007]

He has another motor he's going to be building and for stock ported heads those are pretty good numbers

Sure those number are pretty good. For a Cam and bolt-on 350.

[RamAir95TA]

It's difficult for me to keep giving advice when no one chooses to take it. It's even worse when other people give the SAME advice and it still falls on deaf ears.

[firebird_1995]

The bottom line is this. You are going to spend more money on building a 383 with that kit and have less durable parts than if you went with freshened up stock components. If its torque you are after, call LE or AI and tell them you want a cam ground for more low end torque. Cubic inches alone is not going to get you there.

good eye there got to love typos ... but more on subject here ... the only way i can to think to split the hp and TQ that far is to make a super heavy rotating assembly and bump the compression up a bunch but keep stock untouched heads

motor would be sluggish and pointless but even then 320 hp and 500 tq is unrealistic for the LTx platform

Oh it'll make torque....... for about 1000rpm to 1100rpm? In a TPI kind of way? Could probably pull a Sequoia out of the ground if that RPM was usable. :)

Anyway, the advice here is sound. If you want to dare to be different like others who've ended up having to rebuild or throw away, knock yourself out.

[cholmes729]

I recommend good rod bolts which is all you will need for stock rods, some port work will help, but try to keep the cost to a minimum because you can find some good used aftermarket heads for $1000 if you run across the right deal. You can get a set of TRW forged pistons for $250 if you want to spray it in the future. The stall is a good investment right now, that will be the next thing I am going to do. Save your money on the lifters, you already replaced them. Are you just going to hone the cylinders, and replace the freeze plugs? I really wish you would call me so I can recommend some good local guys that wont screw you over and save you some money. I have been doing this for awhile and I know some people. 4055329470
