66 Barracuda Big Block

It appears from all the measurements I have taken and pictures that @pishta so graciously sent that the factory C body HP manifolds will work.

That would be me. I did it with HP manifolds and I did it with Pro-parts headers. Dont waste your time with headers, HP Manis will be plenty fast unless you plant to run it with J-bars and without inner fenderwells. There is just no room for headers.

Hey @pishta - Can you post up the photos that RustyRatRod was talking about? I'm working on a big block 66 myself.
