421 question: Cost to machine recess to lower compression?
(looking at you, Bart Orleans!)
I have a line on a set of (8) 4.125 / 4.000 stroke Ross forged pistons that came out of a very low-time '65 421 build. My block could easily take the .032 overbore, and would like to keep the stock 4" stroke. Issue: The pistons are flat tops, which means only a pair of notches for valve clearance, and a static CR way too high for -092 /-093 heads if zero decked. If you have done this, what is a typical cost for the setup and cut from a reputable shop? Or does that compromise the piston strength/durability? Thanks! |
