I would also think the standard gears would be fine also and I would think you would need the 4.56 to get you up in rpm power range also.
I ran a 302 in a fox body bracket car, it was only 2950# but ran a 30" radial like stockers run and ran a 4.88. It ran 10.50-10.60 and would trap at 6900-7200. With those little motors rpm's are your friend.
