We have a 73 Nova with a big block 402. It has a 3 speed automatic ratchet shift transmission, 3400 stall converter current tire size 28x14xr50 i have been told and have not been able to confirm that we have 411 gears and also been told we have 373 gears the car is extremely torquey pushing 450 hp after depending on which gears i have what tire size does everyone recommend for racing slicks? Also should i tub the tires or cut the fenders out and leave the axle alone, my current 14" tires stick out approximately 3" on either side of the car.. Is there any advantage to tubbing the wheels? Please advise.
