what exhaustmanfold fits a 454 engine 1975 to 1980
pretty much any 454 exhaust manifold will fit
it should, i just put a 350 in a truck that had a 454 in it previously. mated 2 a 400 turbo tran
Yes. The exhaust would be different.
Well I have the reverse, 454 manifolds on a 350, so I would think so.
Yes, but the big block may need a hi-torque starter.
A 350 is a small block and all the engine parts are small. The 454 is a big block and everything is big. Nothing will interchange.

It depends on what body style the the engine is in, whether it has single exhaust or duals. On my 91 K3500 with a 454 is on the passenger side exhaust pipe next to the transmission. They are usually a little higher up. Hope this helps.
on the driver side head just above exhaust manifold
If the 454 is complete with accessories such as exhaust manifolds, a/c, power steering, alternator, etc., it should be a pretty straightforward swap. Transfer the motor mounts and distributor from the 350. A new exhaust system will likely be needed.
motor mounts are different, exhaust won't line up,
Small block, and big block use the same flywheel. 400, and 454, are both unique, however, in that they are externaly balanced. 400 will not interchange with any other small, or big block, other then 454. They both use unique harmonic balancers, as well.
