- My 13 year old wants to build a 1971-73 Mach 1 Mustang for his first car. We have found a Grabber Blue with white interior base model 1971 Mach 1 to start on.
I want to shave .020 off the virgin 1973 open chamber 4V heads. This is my first 351C build. I know the combustion chambers are huge on the 73 4V head. The .020 cut will square the deck and bump the compression ever so slightly. I am also going to square deck the block by .010-.015. I would suppose zero decking would shave .020-.025 off correct? I would like the compression to be close to 9:1 with the H555P pistons.
