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.

Verdad Gallardo 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 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 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

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?

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.
