probably a 440 with a stroker kit. either that or a 400 to save some weight. I'm limited by the fit of the headers if you use a 400 you have to use heads with non stock exhaust ports. (as i understand it) whichever way it will be about 500 CI. I intend on doing the motor last. that way once i start it up the first time i dont have to wait anymore to drive it.
its gonna be a while but it will be worth it
