Bought it used off a buddy that ran it on a jeep. Anyways I run a 2300 5.2 rod d4 cut head hyd cam 430 lift no port work. Stock d4 intake. Will be turning around 7800 on 1/2 mile dirt. Whats a baseline jet size and power valve to start. The power valve is not stamped and the jets are 70's. Do I need to change the needle valve or install anything else. Our rules allowed us to run 350's this year. I understand every motor and atmosphere is different but im just trying to get an ideal.
