Low Profile 2.5in Exh. Manifolds Gen Iii

Hooker Blackheart Gen III Hemi swap headers are part of a fully engineered swap system that provides maximum component clearances, ideal drive train geometry & clearance for a 3.00 in. exhaust system. These headers fit the 1973-1974 Chevrolet C10/GM C150 2WD trucks with the Gen III Hemi swap and correct directly to BH14308 or BH14309 exhaust systems. These high-quality mid-length swap headers are made from 304 stainless steel and feature 3/8 in. thick header flanges, 18-gauge 1-7/8 in. primary tubes, and 3.00 in. collectors (w/ merge spears). Headers provide clearance to the brake booster, steering shaft, power steering box, starter (both left & right side-mounted), rear sump oil pan, and several automatic & manual transmissions options.
