64 Valiant 440 build
Sounds like how I want to build my Barracuda. Except I'm going small block and a 5 speed for now, maybe a 6 speed later on. I don't have the heart to cut my sheet metal for the sub frame connectors like you did on yours though. not even pin holes in my floor.
Is your 440 internal balance? we make sfi dampers at work for crankshafts.
