340 manifolds..

wish i could find it mopar muscle or one of the magazines did a flow test and the magnum exhaust manifolds flow just as good as the ol' hi-po manifolds EXCEPT there is steering (power) shaft clearance problems...the engine has to be raised a bit. Amazing how far technology has come in 35+ years magnum manifolds are by the billions while those dang hi-po 340 manifolds are like gold, even 20 years ago!
