I'm helping a friend of mine swap the engine in his 67 Firebird. It had a
chevy 327 engine in it, and we're swapping in a 78 Pontiac 400. Two
questions. First, will the motor mounts for an original 67-69 400 work
with the 78 400 block? Second, does anyone know the casting numbers for
the exhaust manifolds for the 78 Pontiac 400?
Thanks!!
