Alrite I have a 2000 Durango 4.7l with a 70mm tb, tb spacer, low temp thermostat, air intake, flowmaster super 10 to duals, and a custom sct tuner that has been dyno tuned. I want a few more performance parts like cams, intake manifold upgrade, heads basically anything that could help add a little more power. Anyone have any suggestions or places online I can order good parts I am having a hardtime finding anything? Or anyone have any good suggestions on part swaps off newer years that help out performance? Any help would be greatly appreciated.
