What is a good combo for turning high rpm?

Well you shouldnt let that stop you. there are plenty of people in the know who know how to build an engine and would be willing to help. I wouldn't let that stop me from putting a Mopar on the track. I mean....it should be no surprise that there is a lack of Mopars in that arena. They are fewer in numbers everywhere else. To me, that would make the accomplishment all the more sweet.
