Best guess on 440 RB motor
Bobby, your tires are 28" tall so don't sweat that, I would run a few 1/8 mile & get your times, don't say anything about what it might run in the 1/4, just play dumb, no one's going to ask **** anyways, half the time they ain't paying attention lol (JK), THEN make your last run 1/4 & your good to go, i know the guys that run the track, so all will be cool, just don't forget your helmet LOL. Let me know if you go ahead of time.
