Factory exhaust manifolds?
Im looking to install a 454 into my 75 half c10 and i have a couple exhaust manifolds that came with the long block. Im wondering if they will fit? The numbers are 3994045L and 353030R. Both are listed as 73-75 police package, nodular iron. Thanks

Yeah they should fit. Granted i cant say Ive held that casting in my hand but the chevelle/caprice manifolds bolt right on and clear just fine.
