satellite engine in a duster, advice?

not true, if you take a 318 out of truck all the brackets to hold the accessories will be wrong and may or may not fit. Does anyone know if the left side manifold from a satellite will fit in a duster engine bay, or, is there a header that will fit. I remember there being not enough room to do anything on that side.

What accessories are you talking about ?

Like Rumble said: A teen is a teen is a teen.Trucks should have different motor mounts, but thats it. If you have a V8 k-frame, all you need is 318 motor mounts.

Usually the radiators out of those cars are 26" plus. Unless you cut the Rad support, a 22" rad is the biggest that will fit.

The right side manifold will probably be the same, but the left side might be different. A-bodys used a special manifold to get around the steering column.
318 A-body manifolds are a dime a dozen, people almost give them away.
Then there are 340 manifolds, and a few choices for headers.
