Schumacher Small Block Hi-Flow Tri-Y Under Chassis Headers

Designed to work with '67 & up A-bodies, '62 & up B-bodies, and '70-74 E-bodies for engine styles 273, 318, 340 & 360. Our Small Block Headers are built only ten sets at a time, and each set is individually test fit for quality and accuracy.

Our new under-chassis, Tri-Y header system gives you high-flow header performance with a custom fit that means you don't have to sacrifice your power steering. Retain exhaust studs in the heads — no more breaking into water jackets! Plus, unlike most headers, it doesn't capture the starter, has excellent spark plug clearance, and is easily installed from the top down. Works with manual or power steering.
