Any suggestions on jet sizes for my 83 Z28? I just dropped in a stock 2 bolt 350 with a Holley 650 double pumper, and it has a dual straight pipe exhaust. It had 67s for the primary jets and i believe it has 76 for the secondaries. I dropped the primaries to 62s and its running better now, but I wonder if i should drop the secondaries a few sizes. It feels like it might be getting too much gas when i punch it. Any suggestions would be a appreciated.
