X heads on a 340 HP potential???

Well, he may just be a diehard chevy experienced builder. Doesn't mean he sucks and the engine will be underpowered. He just doesnt do a lot of them and doesnt have a good grasp on what a "typical" deal might do. That would make sense if it was him that recommended the MP .509 cam too.
He is actualy a good friend of mine. We are always harrasing each other. He is comparing it to a 9.5:1 (chevy) 350 w .202 heads he just built. He does good work and is very particulal, but dont do many mopars. Would you recomend a diff. Cam?
