64 GTO ROAD RACE CAR engine change pics and dyno video

[gtoroadracer]

It has been a while since I last posted, I just wanted to share an engine change for the race car. I have been working on this for the better part of the year. I finally got it finished and strapped in on the chassis dyno at work to break the motor in and make some pulls. The motor is an LS3 Block stroked to 416 cu inch, 3 stage dry sump, Carb. motor with a custom comp roller cam and a SLP / Manley forged rotating assembly. Here is the video link http://www.youtube.com/watch?v=3lcN_YiZbIs Thanks for looking

I Always loved this car! the new motor looks right at home in there! Keep up the great work! If you run at NJMP, you'll have to make it out to RTTS (run to the shore) next year... check out the Racing Events section on here for photos from last years event...

So much for class rules not allowing a dry sump system..... I am very surprised that you switched to a chevy engine. What class does that put you in now?

Looks like a Pontiac G8 or GTO motor to me

Good question, since it is a purpose built track day car there are no rules, sometime I wish there was because you would be amazed on what some people race at the track.LOL As for the change from the Pontiac motor to the Chevrolet LS3 that decision took me about 6 months to make. I have had this car for 27 years and it has had a Pontiac motor in it for all of those years. I have been road racing the car since 1991, I have had some good times and some bad times. The last couple years the bad times became more frequent and I had to learn from the problems and work forward. There were a bunch of factors that I went over time after time and when it came down to the final descision I wanted to give it a try. Which is what Hot rodding / racing all boils down to is "experimentation" and like Monteboy84 pointed out the LS3 motor is available in a 2009 G8 GXP so I am at least kinda keeping it in the family.

I remember the article on your car from HotRod in '06, very cool.

As has already been mentioned your car has been a huge influence. The very first time I saw it, it was like every desire I had for an old american car had been realized in your car. I will say you were the first person who opened my eyes to the pro-touring scene and I still like your car the best. I hope when the day comes, that I can actually build my car (65 Plymouth Sport Fury), that it will be even half as nice as what you've built. Nice work.

Thank you I am glad you like the car, I never thought the car would inspire anyone more than me. I hope you can build your car the way you want.

Nice job! I love it! I think I'm going to go a similar direction with my Chevelle, but I intend to stick with a BBC (aluminum though).

Thank you, good idea keep it light as possible the aluminum block will probaly save you about 100 pounds plus it will run cooler.

Motor looks amazing along with those headers/exhaust.
Nice work.
