i was wondering if I can use long branch exhaust manifolds on my 1970 tempest 400 4-speed D-port heads. And if so what are the collectors inside diameter.

Long branch manifolds fit full-size cars, first gen firebirds and gp's (69-72), will not fit A-bodies.

IF you take a lot of measurements, are willing to modify the frame and crossmember (notches), and have a solid frame, you can put Long Branch manifolds into an A-body. I did it on a 64 GTO
many years ago and a man named Tom Jeffers did
too on a 67 A body. A LOT of work!
