Real talk: exhaust manifolds on 360 Dart

TT5.9mag said

In an A body? I don’t think there are any 360 manifolds (driver side) that fit an a body. That being said, I bet the 340 hp manifolds would show +- 10 hp on a mild 360 over the 360 manifolds, and both would be down 15-30hp on a good set of headers.

Yeah, the 360 A bodies kept using the late (72 and 73) 340 manifolds. As far as manifolds go, I wouldn't mess with anything other than the 68-71 early 340 manifolds, as they were the best ones. The later Dakota and 1500 truck manifolds flow well and have 2 1/8 outlets. People have made them work but I don't know what all it entails.
