I'm looking to build the power of my 289. I've already got a Edelbrock Perf. RPM Intake and Edelbrock Carb, Hedders, and the exhaust done. I need more power!! I want to run with the big boys...5.0 stangs, 350 chevys, ect. Besides what I already have what are your suggestions. This is excluding a supercharger and nitrous. Thanks for the help.
