Hooker BlackHeart has quickly become the leader in engine swaps and we are excited to offer our 68-72 GM A-Body LS swap headers in mild steel with 3 different finishes. These 1-7/8" x 3" long-tube headers provide excellent ground clearance as well as component clearance. They are designed to work specifically with our Hooker Transmission Crossmembers (P/N 71222007HKR or 71222021HKR) and Engine Mounts (P/N 71221006HKR or 71221007HKR) for a trouble free install
Features:
1-7/8” primary tubes and long transition 3” collectors with merge spears for maximum flow and increased exhaust velocity
Tight-tucked design provides maximum ground clearance
O2 bung locations optimized for wide-band O2 sensor operation/reliability
Optimized tube bend geometry clears all factory stock vehicle components (including the A/C evaporator case), allows for easy starter motor/spark plug serviceability
Compatible with all GM automatic and Tremec T56/T56 Magnum transmissions
