something us stock pcm guys can't do

My first Firebird ran 7.94(1/8th) with a bone stock motor, DFI, long tube headers, TH-350, and gears. I added a cam, valve springs, and a better transmission and it went 7.10.
When I first built my Camaro I built a cam only L99. It ran 7.85 at 3300 lbs. I then built an LT1 that went 6.76 with .030 factory pistons and stock rods. The last motor in the car had all of the best pieces in the bottom end and ran 6.61.
There were also a lot of other LT1's and LT4's in both cars, but these were the highlights.
The Camaro also sixty foots in the 1.3's on 9" tires. I bet that's not possible either?
No dyno sheets, but a bunch of IHRA National Records over the years.

The first thing I did on my Firebird was toss the factory PCM. Even with the bone stock motor. An aftermarket computer is the only way to go. I change gears, transmissions, cams, headers, etc. so often that it would be a nightmare to work with the factory PCM. Not to mention that you can rev over 7000 with an aftermarket PCM and you can dump all of the emission controls, etc.

I made ~385rwhp with a small solid roller. The shortblock and heads were untouched, reving to 6600rpms.

This post should read : For newbie Gullible readers :

2nd off why put the time in on something like this. why would u want to make max horsepower on stock lift. your just asking for something to break.

oh yeah i made 50hp gains from a coldair intake and a catback

You guys understand there are fast cars that arent on the internet, I can belive high 300s, I dont know about 400s but high 300s I can belive.

Thanks for the support. I really don't understand why people post some of the negative stuff that they do. Each to his own I guess!

Here's the Camaro at the Kinston IHRA race last year.

Yeah to those that don't believe this guy you really need to read up on stock eliminator.. the original question was how much hp MAX has been made on stock heads and he answered the question.... he didn't ask was it a street car cause obviously it's not a streetcar... can someone driving around in their streetcar made 420RWHP on the stock heads, probably not..... can someone with Gen VII DFI and a gigantic cam with stock lift do it? Not easily but it's possible especially with a race car like that... Much props to you man for making that much power.... I made 422RWHP with a budget built 355 with a hydraulic roller 236/242 cam with .556/.576 lift and a budget set of stage ii LT1 heads and I thought I was doing something (then again it was my daily driver so maybe i was).....

And to the person who asked why would you want to make max power on stock lift BECAUSE THOSE ARE THE RULES TO RUN IN STOCK ELIMINATOR..... read the post before you reply man...

I must say this thread has run its coarse...

BTW you won't like driving that engine on the street. But it did answer the question

slick1851

Stock class is like hidden in the dark, alot of people dont know about it. Its not talked about a whole lot. Is there any sites etc were I can get alot of info on it, i love real cars racing.

The funny thing is that the car cranks fine in all kinds of weather. It never overheats and idles at 1100 rpm. Gas mileage and valve springs would be the killer!
I only reply to threads like this because I think that a lot of guys are of the opinion that the factory parts are not very good.
I race Stock Eliminator because it has the most restrictive rules in all of drag racing. I was gung ho to build an LT4 for the LS1 Tech Series. I liked the fact that they had a fixed set of rules. It was a shame that they cancelled. I think that an LT4 would have been able to run with the LS1's.
That other Camaro is not my car. It's amazing how many of them are running IHRA/NHRA.

Good class racing sites are;

so just curious, what do you do to these engines to make them achieve this kind of power levels on a pretty much stock set up??

Frank95z

Good job Gizmo. I am Frank95z and I run a pump gas stockhead street car. Very low tech compared to a stock eliminater car. I made 357rwhp but my stock computer has not been tuned for the latest cam. I run DOT tires and shift at 6200 with 3.73 gears. I've run 11.27 at 118.90. Frank95z

You guys should give people more info, you know the LS1 boys have been making a bad name for the LT1.

It's really not just the motor. To make that kind of power you have to work on the whole drivetrain. That means light weight everything. The less HP that you lose thru rotating weight the more you see at the wheels.
The trick to the motor is the blueprint. Everything is right at the edge of the NHRA specs. That means .060 over pistons and about .013 extra stroke (.070 and .015 are the max allowed). Rings play a major role. So does oil control. I run a truck pan with four quarts of Mobile one. Most of the oil drain backs are plugged to stop oil hitting the cam. The hydraulic lifters are modified to allow more rpm. The trick to getting the heads right is the valve job. A three angle job is allowed, but it can't exceed 1/4" top to bottom. Aftermarket 1.94/1.50 valves are allowed (no titanium). The combustion chambers are all matched to the same volume. The block is decked to .015 in the hole and a factory head gasket is used. Everything is balanced and an ATI damper is used. The alternator is the only accessory required. A good assembled short block takes 15 lbs or less to rotate! Really the motors are good bit away from stock. I use the best parts that I can afford and the best engine shop (Warren Racing).

Frank,

I think we met at Thunder a couple of years ago?

I am really tempted to build an LT4 and run the N vs S race in September just to find out if I can outrun some of the LS1 "Big Dogs". Last time I tried it I killed the motor. I still got my picture in GMHTP! Maybe I could do it and post all of the details on here? It would have to be a low buck project made up mainly of parts that I have sitting around. What do you think? I would need someone to help me put pictures on here.

You dont do anything with a stock LT1. its a waste of time and money. if i had a LS1 and a tight budget i would definitely consider it. You just get way better results with a stock LS1. This is why the LT1 has a bad rep with LS1.
