Street Friendly Build!!!!!

[david068513]

Ok, I need some opinions. I want a street friendly motor, this car will be street driven alot to shows, strip, around town etc. so it needs to be street freindly, fast, and reliable. I am starting out with a 1994 Z A4 vert. its gonna get full susp., roll bar, race seats in front,sfc and stb etc. built rearend and tranny but idk how to go about the engine. this is my first LT1 and my first vert. Should I bore the engine out? stroke it out? stock cubes? its gonna get heads, cam, intake,TB,longtubes,full esxh., everything basically. Just need some help. I want to spend a max of 10,000. No weight reduction. all creature comforts and run low 11's.


help?

383 and call Lloyd Elliot for your heads cam and intake work. Get a 12 bolt rear end with 3.73s or 4.10s and a torque converter oh and drag radials

who is Elliot??? where are they located at? Also why a 383? why not a 355 or a 396(clinder walls to small?)

lloyd elliot is a wellknown lt1 head porter located in texas i believe. A lot of people use him and he gets a lot of power out of stock heads. If you want to run low elevens NA then i would think you would need to stroke it to a 383 or 396. Most people go with a 383 cause its cheaper and there are a lot more kits out there.

Are you wanting to run NA or spray the motor?

[AChotrod]

Im gonna do a 355 and plan on mid - low 11 on DRs, but i figure with the weight of the vert a 383 would be better for you and a 396 requires alot more block work.
Lloyd is in texas and does amazing port and custom cam work call him!!!!!

All motor. I will check into Elliot when I start ordering stuff but I think I am gonna go with aftermarket heads. I am almost set on a 383 but want opionions.

You should also check out advance induction

Most people will tell you to stay with the stock heads unless your wanting 500+ horsepower.

Im going with a 383 when i start my build. (which is gonna be a while.)

thanks for the link. 500 hp sounds great to me :laugh: It will be quick when Im done. :secret: and will lift the front wheels off the ground :whistle:


what build you talking about? the SS or formy??? I remember you saying you wanted to build the SS. I have a uncle with a 383 LT1 running mid 10's on spray and 11.0's on motor. I am gonna talk to him about what to do...

[AChotrod]

LE ports after market heads also.
Most out of the box AM heads will need the port work also to run those numbers. He makes stock heads flow better than After market heads though.

[1badz]

And makes aftermarket heads flow better than.. everything :D

For a street car, I'd go with a 383 to keep the TQ curve workable, and it'll eat some extra camshaft over a 355 while keeping it streetable. Then I'd plop on a set of smaller aftermarket heads (but larger than stockers). Think Dart maybe. Sprinkle that with an LT4 manifold if you can find one, or mod an LT1 manifold to work otherwise (skip the Edlebrock -- not enough plenum volume to adequately work). Top it off with a cam ground for your setup from whomever ported the heads. Properly done, you should see around 450ish RWHP, 400-425ish TQ with a VERY manageable powerband that'll idle around on the street just fine.

thank you for your ideas. Why are the LT4's manifold hard to find??? So I should port the aftermarket heads huh...Also what do the dart heads flow???

[Fastbird]

GM stopped production on them. The eldebrock manifold would be a good choice if it didn't have LESS plenum volume than a stock manifold. Longer runners mean poop when you can't get air into them.

Reason I mentioned the aftermarket castings is because you can get a larger runner and more cross sectional area for air movement, something that a 383 is going to NEED to perform in the upper area of the powerband. Why do you think 90% of the strokers out there aren't making more than about 420 RWHP?? The heads just don't support the air movement required. AFR's have always been lacking IMO, but enter Trick Flow (ported obviously) and I've seen many 383's putting down 450+ with the same cams as stock headed strokers making 30-50 less at the ground. Darts are a decent budget choice. I haven't seen results on AFR's eleminator line (I think that's what they're called) yet though, those looked promising.

If I was building one myself, I'd do a 383 with a set of milled Trick Flows and a mid 230's high 240's low .600's intake and upper .500's exhaust lift 112* lsa cam (very general specs, I know, but it's a setup I'd like to see). I think properly done that should make around 450-470 on the top end and with the stroker be quite manageable down low.

I would do a forged 396 stroker with Advanced Inductions best heads and a mid 230x cam. You'd have enough torque to pull a house off its foundation.

^^^^^^^:devil:

Would the cylinder walls be too thin for a street car? If you put alot of miles on it will it hold up?

[Fixxer99TA]

Of course, if its built correctly.

A 396 has the same bore as a 383. It's just the stroke that changed.

[david068513]

thank you, I understand that But Will it be as street friendly.

Ah. I thought you meant bore it that far... :jest:


so would a 383 or a 396 be more street friendly? Which can you get more power out of?

13 cubes isn't much. The issues is that the 396 you have to clearance quite a bit more from the block for the stroke, and a LOT of times that's extra work patching up water jackets from going too far. No biggie, but it's extra time and money. They'll both make about the same amount of power per se.

[JoeliusZ28]

more cubes = more driveability (in comparison to your cam specs)
