Overtired or Not? - 02/04/09 06:59 PM
Ok, here's my dilemma.
I have run a 14.0 x 32 for several years since we back halved the car. It is now a 4 link at 3200lbs. My question is whether or not there is something worthwhile to gain by stepping down on tire size. I rarely have tire spin but one wouldn't expect it with this much tire and this little power. Should I step down to perhaps a 29.5 or some kind of 10.5 combo? What do y'all think?
Current combo:
416SB
575hp, 540lbs tq
904 w/ 2.74 low gear
5:13 Dana
4 link at 3200lbs with me in it
Strange double adjustable shocks(rear)
8" 5500 converter
Launch at 4800, shift at 6500, traps at 6900
Current 60' = 1.39-1.40, ET = 10.49 at 123mph
