I should have said: an original Ford fe block, "with a few new parts"!
It's all about air flow! I have a turkey pan for shows. But remember 427sc's were competition cars, they ran a single carb & turkey pan w/out air cleaner! The street cars had 2 carb's and small air cleaners. The turkey pan only works well without an air cleaner. I don't want to drive without an air cleaner, & the small ones are too restrictive. So, for daily use, I have the larger air cleaner.
But the block is an original 1966 FORD block. = Braggin rights!

P.S. That is, with a few new parts!
