...TBH I think the 2 1/2" single will cope OK if the motor is done by 4500...
...and apparently Ma Mopar thought the same thing with the OE Dakota's single pipe being a 2.5" unit. And I mistyped - the cam I'm running is a Comp unit #20-745-9: 212-218 (264/270), .480/.480, on a 114* LSA.
but I would have thought a 280 duration cam would wake a 360 up a bit more than that
ya I dunno - I haven't really had a chance to do any real street time - no full-throttle runs yet...mostly just low rpm trail runs.
Meantime, if anyone else has input pls feel free to keep the conversation going
