www.pettisperformance.com Jason is as sharp as they come. He's building me a ZL-1 489 currently. I went out to the drags Saturday and Sunday and watched the Mustang he builds the engine for and crew chiefs. It's a 440 ford with a supercharger that makes 2500 hp at ran a 6.71 on Saturday. Not the cheapest but a killer reputation. Let him know I sent you.
