Mike C Posted March 23, 2002 Share Posted March 23, 2002 Is anybody running straight dump rams horns on their cars or just the turn backs? Instead of block hugger headers it seems you could angle mill and spot face the Corvette 2 1/2" Rams horns if straigh dump manifolds will work. Either extrude hone or have somebody like Brezinski flow them and have the best of both worlds. I replaced a set of 1 5/8" headers on my JImmy wiht the Corvette 2 1/2" dump manifolds and was REALLY pleased. Extremely quiet in comparison and excellent power delivery. With only a 266 cam in it I can't make a testament to top end power, but a fuelie 'vette would pull 6500+. A 2 1/2" mandrel bent 90 deg elbow to 2 1/2" to 3 (un) reducer and 3" exhasut out the back. Any thoughts on this? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 23, 2002 Share Posted March 23, 2002 In the JTR set back position,there may be a steering shaft clearance problem with the ramshorn straight dump on the drivers side and requires a rearward dump milled 2.5 degrees on the face of the exhaust flange. The passenger side will take the straight dump but still has to be milled 2.5 degrees to clear the frame rails. Quote Link to comment Share on other sites More sharing options...
