Ordered a gear vendor, help with deciding gears

Depends on the OD’s ratio and rear ends gear ratio.
Using an OD trans, 4 or 5 spd is IMO, a good idea. YOU just have to figure out what you want your cruise speed to be and at what MPH. Which works in conjunction with your tire size. This equation should work well with your cam.

what do you mean cruise speed? Like highway cruise speed. If so 70-72mph.

I originally ordered it (late Friday) because I wanted to run high gears like 3:73 or 4:10, and thought if I had a hood nitto 325 tire and could get it to stick I could have a hell of a launch.
