The header collectors on my '75 F-100 4x4, 4-speed are rusted out beyond welding help. The engine is a 360 FE. I am looking to maybe go back to a cast-iron set of manifolds. Rock Auto lists a pair but makes no mention as to 4x4/2wd or auto/manual trans. Did all the FE trucks that year use the same manifolds? Thanks in advance!
We're not talking about all out performance. If the cast exhaust manifold correctly bolts up to the head and the dump is located so exhaust shop can build a down pipe, you're all set. Go for it.
