What's the ratio on the Glide? If it's a stock planet it needs to be 1.76. The 1.82s are week and wont last long with any power. If the car weighs 25 with you that's pretty light and the Glide should work well. My car still weighed almost 3k when I switched. It lost about a hundredth 1/8th mile and 2 hun. 1/4 mile but the mph went up a little and so did the consistency. That was with a pretty small motor.

With the data you provided my opinion is the car shouldn't slow down at all. The initial hit might be a little softer but the car will hook better and pull harder through low and should ET just as well, even in the 1/8th.

Every body talks about how quick their 60 foot times are but so what? Fast 60 foots mean absolutely NOTHING! Consistent 60's mean EVERYTHING.
