I do not really have the money to spend on the 427 Its going to be a major job, so I was thinking for now just putting this in with a clean up, good runner 10.5 comp with a small solid roller 5.75 5.88 227 and 232 @ .050 on 112* made good power and I can use the money to have the car ready for spring, and just fix the 427 next summer.
