Probably going to need a carb adapter that you can get from Holley, and at the least 454 injectors. Then you're going to need custom chip work done or learn to burn your own.

But yeah, you could use it.

GMPP makes a kit just for that conversion with all the stuff you need. But for about the same price you can get a ramjet and a bunch more power.

damn, that's a little more than I was thinking, what else would I need to buy to do the swap if I bought the ram jet? what if I bought the zz4 with the kit, what else would I need? guess I will need headers, but what else do I need?
