95 Dakota build

As I said, bigger cam.... skip the cheap cam.
If your going to do this with stock heads, the cam required will be more than an extra 20*’s or duration and more converter will be a plus.

Oh wait... I said that already... nevermind

Being the engine is a roller cam engine to start with, look at a solid roller and lifters. A solid flat tappet cam can also be used for less $$$.

IMO, with this heavy truck, your looking at ported heads or aftermarket heads. This will offer a better top end charge due to the added air flow and allow less cam duration.
