I'd like to be able to run there this season but need to know what gear I'll need with a 604 engine? If nobody wants to let out there secret just pm me and at least give me a gear range I should have with me when I go.
Depends on what you like to turn your motor. There are lot of different ranges people run out there. I ran a 637 most of the time, but I ran the 602 motor. The previous year I ran the 604, and ran close to the same gear, sometimes running around a 648....so I would have gears ranging between 620-648, but I'm sure there will be other opinions on what gear to run, but that is what I used.
