Looking for Advice on Jets
Here is my current set up: 389 bored .30 over, 093 heads, dished Ross pistons, 68 cam, 4 speed and 3.23 ratio rear. About 9:1 CR. I live about 52 feet above sea level.
I am running a 65 tri-power. The center carb is jetted with 63 size jets currently. I am running a little rich and have played around with the A/F needles but it still runs rich. I have some 62 and 61 size jets on hand. I am thinking of using the 61's. What are your thoughts?
