my heart has always been with the 250 292 chevys they are capable of a lot of power and torque with relative low mods i am building a 250 that will be injected with six throttle bodies and use the megasquirt efi system of course it will be of the homemade veriety as all my stuff usually is. you can get banned from nhra for being to creative it seems! remember buddy ingersol? buick v6 twin turbo? he was faster than the pro stock class and they boycotted him back in 1986
