Quote: I just picked up a set of 1957 Hemi Industrial heads and I'm thinking FED build using maybe an old Poly block since Hemi motors are hard to come by and I heard most of the LA reciprocating parts fit the poly block.
lol I'll just add it to the current list of projects including:
1970 Dart Drag car 1969 Barracuda 383 formula S build 1969 Roadrunner street/strip car build 1969 Roadrunner Drag Car build 1969 Power Wagon 4 door build 1971 Power Wagon short bed build 1967 Camaro Drag car build 1981 Malibu Drag car build 3 Cummins trucks with auto trans issues 3 Chevy Suburbans 1 running 3 Jet Boats in various stages of disrepair
Not that I want to mess with your project count but I'm pretty sure that those heads will only fit a Chrysler poly block up to 58.
The Poly "A" motor won't work because the bore space is wider.
but I'm pretty sure that those heads will only fit a Chrysler poly block up to 58.
