W2 Mopar inspection w/RAMM

Cam wise, I’d look at a longer exhaust duration cam. How much? No that is a good question!
What is the intake to exhaust flow balance with the exhaust manifolds installed? Also, would you bother researching the exhaust pulse wave and a pulse wave termination box(s) on the exhaust pipe?

Is been demonstrated before that going fast with factory parts can be done. They key is knowledge and exacting knowledge of what is going on with the engine from air cleaner/filter into the engine to the exhaust out to the tips.
