That is the point. You have a fairly heavy mid size truck with a 318 that has mild mod work that is in the same time bracket as a big block roadrunner. Not to dog the older la motors but the newer magnum engines do make more power while keeping reliability.




Just my opinion of course, but I don't think the performance gain of longtube headers would be worth the effort in the OP's 4x4 case....hey some folks just want'em.

Do some research on the test comparisons of headers to cast manifolds that have been dyno proven .... woke me up
