Dport pontiac Ram Air manifolds with nearly 20% more flow than original castings or the Chinese manifolds sold by other parts places on ebay.
Heres the quality difference: USA foundried, machined in my shop. Blueprints provided us by Pontiac back in the 80s for the tooling. We guarantee these items for Lifetime. We have 35yrs in the business.
Here's what they can do: Recently had a customer dyno new motor and it came in at 604 ft/lbs tq with 4-tube headers. Made subsequent pulls with our Dport high flow and 2.5" dwn pipes and peak torque hit 592 ft/lbs. And peak torque occured at slightly lower rpm which is what we all love on the street. No tube header blues--gasket leak/bolt access/ground clearance issues.Fit 68-72 Gto/LM and 70-81Trans Am. Doesn't fit 301 v8. Shipping is 48 bux.thanks, Paul at RamAirRestoration.com
