1973 Big Block HP Exhaust Manifolds - 03/09/22 11:00 PM
I have some questions if someone can shed some light? Do all HP exhaust manifolds for 383, 400, 440 big block engines have the same air flow? I bought a set off a 1974 Dodge Charger with a 400. Will these manifolds bolt up to a 383? Someone commented to me they are smogger exhaust manifolds.
