Has anybody tried running a Holley pro-jection setup on a 250 before? I have a 250 I am planning on using as a rockcrawling motor and I am getting holley projection kit to adapt to it somehow. It is a 250 out of a 1970 C10 pickup.

The main question is how do I adapt the throttle body to a 1 barrel intake? Or do I need to get a 4brl intake? If so where do I get one for a decent price?

Has anybody run this setup on a 250 before? How did it run and anything you recommend? Thanks
