Add some headers, and call Cope or someone for a decent torque converter(this is the big one). Get a timing light and learn how to read plugs or maybe find some one with an LM-2 or other fuel/air sensor setup.

The performer rpm and holley 750 are fine for your intended goals. S/F....Ken M

You have a 2k stall convertor? I run more than that in my truck. A good converter, properly matched to your combo is invaluable. In and of itself will make you feel and be able to more efficiently use the power you already have.
