lt1 306

[z28rssscamaro]

hey guys ive got a 97 ws6 firebird formula im redoing the engine in it and i was wondering if i could get some opinions on my chioces of parts that i wanna get ok here the list
comp 306 cam
1:5 rollor rockers
2.020 1.60 valves
ported heads and intake
58mm TB
30lb svo injectors
hooker long tube headers
the block is bored .20 over
and im haveing it all balanced

i just kinda want som input on what you guys think and guesses on about how much hp ill be gettin

[RamAir95TA]

Instead of picking parts and guessing HP, pick your goals (HP/ET) first, THEN choose your parts.

Who is porting the heads?
How do you know you need 30# injectors?
What are you doing for a bottom end?
Why only 1.5 rockers?

IMO, get a heads/cam package from AI (www.advancedinduction.com) and let them supply you with the parts you need. LE is also an option.

[95formula383lt1]

380-410 guessing completely, how ever im not a AI nuttswinger and have heads that were ported by percison motorsports of florida with 2.02/1.60 valves, ported intake, 58mm tb, an 1.6 rockers and a cc306 cam myself so i know nothing.

[Dave357LT1]

A.I. is good and all but i swear if i had a bad window motor some people would tell me to send it to A.I. and have them port it and it will work better. Ur prob right around 400hp

[RamAir95TA]

Not sure what you guys' problems is, I recommended two good head porters, not just one. LE is recommended just as much as AI.

And just because you have ported heads and a 306 cam doesn't mean you know anything either, especially since you don't even provide any results, be it ETs, HP, dynos, etc.

[FSTFBDY]

Lol@ dave. Of corse your gonna get the AI and LE comments. Those are the 2 biggest hitters out there known for producing good results. Its just the same as the SPOHN suspention nut swingers.
To the op...
Either head will get the job done. If you have the $ get some nice
Afr 195 or 210s. Depending on your goals. Figure that out 1st. Then do your parts shopping.

i clearly said i dont know anything guess u missed that one. go back an check threads ive posted in, u will see that i also recommend AI or LE im not more partial to one or the other like them both equally i will not post links to one an not the other i always post both links. My car has been on a dyno an has been down a track. My combo is perfect right now on my somewhat stock bottom end for what im doing. My 383 will have a different set up an id never throw stock castings AI or LE ported or not. The only thing that aggravates me is every thread on here has a AI link in it acting as if there no other person on the face of the earth can port a head an have similar results yes with there CNC program its hard to beat, but local shops can meet ppls goals or better as well

and i completely understand Joe you are having great results with AI an ur car is movin so u support them more then any other. But i hate how ppl act like there are no other options.

[FSTFBDY]

Wow someone soft skinned? If you go back and read I said @ dave reguarding his ai and window motor comment.

I know everyone nut swings off ai or le heads. And your right its hard to compete with a cnced head like ai puts out... But there are thing you just can't do with a cnc like you can hand porting. I have a guy back home in ohio who does awesome work on heads. Did my lt heads. They are = to an. Le1. I'm actually looking for another set to send him for a major port job and a 2.95 sc pulley.

Its just common fact someone askes who does good lt head work and 99.999% of the time your gonna get le or ai for an answer because they are the 2 main stream lt head porters. Fact if people go with what's known rather then taking a chance of having a local shop do it.

chris my post wasnt directed to you. i understand i Ive stated on a few threads i recommend AI or LE depending on ppls goals. I have been in the lt1 world a while now an am completely aware. what LE does is a work of art that very few ppl can do, AI's results have been great with there CNC program. But like i said there are other options and far from soft skinned just realize not everyone wants to drop 1900 bucks or more on stock castings and a cam.

[FSTFBDY]

Totally agree with ya there on the 1900 +/- $ on stock castings is a lot.

I never said there weren't any other options...I said AI or LE. And you said yourself their CNC program is hard to beat, so why not recommend the best to the OP and let him decide if it's overkill or not? I've got first hand experience and tremendous success with them and I recommend them in the hopes that other people will have HALF the success that I have.

And I'm sorry I didn't post LE's link, so here ya go OP: www.elliottsportworks.com

This is a case where the bang for the buck is tremendous. You certainly get what you pay for. If you think $2000 for an extra 100 to 150HP+ N/A is too expensive, then just spray it.

I said it before...AI is for the guys who want the balls out performance, LE is for the more budget-oriented owner who is easily pleased. And the results support this.

JMHO. Sorry this is turning into an AI vs. LE thread.

[95formula383lt1]

while u have never said there weren't other options check almost every thread u posted in about heads or a cam an see u 95% of the time ether post about only AI or just lean very hard on AI. Like i said with the results u have had i understand that. But im willing to bet when u asked that question in this thread to the op asking who is porting his heads, if he said someone local which im sure he prolly will, u would try to talk him outta that. I agree with you in many ways but if someone can find a reputable local porter that has had good or great results in the past why fork out the 1900 bucks that they prolly don't have to get similar results... an just saying i do believe i read a few post from u trying to lure ppl away from LE due to recent results.

[95formula383lt1]

personally what im doing is TFS 21s with AI port work an just maybe a solid roller set up up or a great HR cam from AI, but i will not pay 1900 for stock heads on my motor. So dont think im hating on AI and making it a AI vs LE thread, cuz im not. :peace2:

[RamAir95TA]

I lean on them all the time because I have results to show for it. What's so wrong with suggesting what has worked for me? And to be honest, any time I post about LE is only to please the LE fans to prevent threads like this. I don't try to lure people away from any vendor...I post results and experiences and let them make their own conclusions.

If you perceive my posts differently that's not my problem. Don't make me out to be the bad guy for suggesting what works for me.

[Lawhead]

I mean why would you only expect half the success for others? If the Bottom end is built up to par and fueling system is up too and they get the same AI package shouldn't they be running VERY close to what your running?

[BLK95-Z]

LE is for the more budget-oriented owner who is easily pleased. And the results support this.


This is complete bull shit. Do you have the track times for all the top ends Lloyd has done? Send me a link to these results please.

[95formula383lt1]

not making u out to be a bad guy man ur not the only one doing it ether. Like i stated u have somewhat of a right to be a supporter u have results, not everyone has had results as good as urs. but ppl should know they can do very well with other options.

[RamAir95TA]

I meant "half the success" figuratively speaking, not literally. :)

I don't need to post anything....they have their success posted on their webpage.

When it comes to stock castings, AI has the faster end of the spectrum. If it hurts your feelings I'm sorry.

I think I've said enough...I'm done with this thread.

[Lawhead]

Oh really now? would have never guessed an AI package running a 20.


But I knew what you were saying :frustrated:

[FSTFBDY]

RamairTA. 2000 is a lot for a stock casting head. I have a fraction of that into my heads cuz I had a local guy port em who I know is just as good as le. He's just not as main strean so charges accordingly. I do agree Good parts and work cost $ but if you shop around you find just as good for a buck less.

Hell im not one to skimp. I have a callies 383 dragon slayer crank , je custom blower pistons , supercharged ,etc...

It pays to shop around. And with anything if you have good results with a certain brand of corse your gonna support em.

It doesnt hurt my feelings at all but to say "LE is for the more budget-oriented owner who is easily pleased" is obviously just YOUR biased opinion. Lloyd ports heads for serious racers as well as "easily pleased" budget oriented owners.

I can't count how many times I've seen someone suggest AI to someone, only to have them say "well I don't need all of that for the cost, the LE1 heads will work fine for me." I'm sure with enough searching through the forums you'll find the same thing, so this isn't my opinion, it's really fact.

I know Lloyd ports for some of the big guys, but from what I have seen those are mostly aftermarket castings. On occasion his stock ported castings make their way onto a race car build, but that happens far more infrequently than AI.

[z28rssscamaro]

ook well my goal is 400 hp and i wanted 30lb injectors because i dont have injectors anymore and i heard that was a good size with the cam that i have i also work at an auto machine shop so ill be doing all the work myself and as far as the low end goes i turned the crank and im getting it balanced thats all ive done soo far

[popo8]

I just wanna know if I am the only male that cringes at the term NUT SWINGER... it sounds so painfull and I can only imagine it would stretch a sack to the ground...... then your forced to wear tighty whities because if you dont the bag will hang down and drag as you walk... brush burning and cutting the skin, which could lead to infections etc..... I mean is it just me that thinks like this....
