0.50 may be a little optimistic for the 1/8mi but think about this: my original set up on my camaro was a mild 355, the car originally had 2.72:1 rear gears and ran around 14.00 in the 1/4mi and 9.00's in the 1/8th, once i switched to a posi carrier and 3.73:1 gears i started running 13.30's in the 1/4 and 8.40's in the 1/8th. that's about 0.100 shorter in the gear ratio but also got me 0.6 tenths in the 1/8th. my trap mph didn't change but by maybe 3-5mph and that was in the 1/4
