426 street wedge cross reference
Hello. I have a 65 polara with a 426 street wedge. I have new pistons, cam. I suspect the remainder of parts are 440 interchangeable but cant confirm. Anyone know?

Pretty much every thing except pistons and the heads are different. It will have the closed chamber heads, so if you use the later open chamber heads you will loose compression... That may be a good thing if it is a street motor
