I crashed my hot rod, gremlin x, 550 hp 401. Putting the 401 in my 82 j10. Gotta have 3in exhaust! My long tube headmans exit so close to frame and Tranny, I don't think they can fab 3in to attach? Was thinking shorty headers might work? Anyone got 3in, or even 2.5 in duals from headers? My current 360 exits through 2in. Dumps in front of rear wheels. Help?
