Center Dump Block Hugger Headers for Gen 1 SBC 265 283 302 305 327 350 400 V8 Stainless Steel 3 Bolt Shorty Style for Street Rods 1955 1956 1957 Chevy Hot Rod Swaps Not for Side or Clamshell Mounts

FITS TIGHT BUILDS & CLASSICS: Center-dump shorty headers for Gen 1 Small Block Chevy 265-400 V8 engines. Ideal for 1923-1957 street rods, Tri-5 Chevys, early trucks, and custom SBC swaps with front engine mounts. WILL NOT FIT SIDE MOUNT OR CLAMSHELL SBC ENGINES: Not compatible with vehicles using stock side engine mounts (1958+) or clamshell-style mounts (1973+). Header collector exits at center ports and interferes with most frame brackets in these setups. DESIGNED FOR BLOCK CLEARANCE & EASY ROUTING: Tight-tuck design keeps tubes close to the block and above the frame for clearance. 3/8" flanges, 1-5/8" primaries, and 2-1/2" 3-bolt collectors for easy exhaust hookup. POLISHED 304 STAINLESS STEEL: Durable, corrosion-resistant stainless with TIG-welded seams and mirror finish. Includes gaskets, hardware, and collectors. CHECK YOUR BUILD BEFORE ORDERING: Will not fit angle plug heads, power steering boxes (some Nova and G-body), or vehicles with steering box directly beside collector exit. Use with flexible dipsticks and short oil filters for best results.
