I’ve seen or read many articles about you guys and the things you’re doing. I wish I could afford one of these. Please keep up the great work and ideas for keeping this type of vehicle a reality. One day I might win the lottery and be on your doorstep. I own a 72 vette that I hope to resurrect one day soon. Thanks and keep up the good work. Chevrolet’s forever. Jim
Jim, thanks for your appreciation! Its been a great opportunity and has been fun making people happy with these builds. Good luck with the 72′! Maybe someday it will have a LSx engine in it! Howard
What is the cost of the LS 454 package with the other tweeks you do on the 2010 camaro? Do you have a price list?
I would contact Dan Carlton at the DeNooyer Performance Division regarding pricing. He can be reached at (518) 526-0412.
How many horsepower did it produce and what is a siamese bore? I also have a 72 Corvette and I think that motor would tear it apart, But what a way to go!
I can’t wait to see performance reviews from this LSX 454 Camaro, Thanks for the fine work you put out from your shop.
Hello everyone! I’m a wholesale parts associate with Denooyer Chevrolet/Performance Division. I’ve added a link to General Motors Performance Parts Website If you would like to read (more) about the LSX family. Make sure you scroll down to the 454! Enjoy!
