I have a 00 GT with the saleen roots blower running 10 psi. I cracked cyld #2 due to detonation. I have to take the motor out and have spoken with the machine shop and they are happy to do the work but I an in need of help selecting a good bunch of parts to rebuild with. I want a much stronger short block, cams, and I am going to have the assembly balanced. I want to stay under $3,500 for the rebuild including the machine work. PLease help with suggestions. I regularly drag race the car so the motor has to be stronger than it was before.
