LS1/LS2/LS6 Cathedral Port Carbureted Base Only (Plenum-Top-Mounting Fabrication Flange Available)
The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!
NOTES: These parts should be used for the following applications: Racing/Performance/Street Rodder where hood restrictions are NOT a consideration.

FAQs
|Q. What is an Intermediate Brake Line?
