PG gear ratio?

IMO, you made a great choice. That is an outstanding deal! I think the 1.80 gear is just about ideal for 355-555 inch engines. Bracket stuff, not class cars.

Just remember to stay on top of the band adjustment. I'd check it before every event.

Have fun.

The band they use is the stock band. I spoke to them about this and they feel that the stock band is very good and holds up just as good as the kevlar band and it doesnt need adjusting as much as the kevlar. How should it be adjusted anyway? This is my first glide besides the one that just broke and I only made 4 passes with it.

Whats the difference between bracket cars and a class cars?

L79, the adjustment calls for tightening the screw to 72 inch pounds and then backing out 4 turns. I think it was 63 corvette (Rick ?)that suggests just snugging it down and backing out 3.5 turns and that sounds perfect to me. You'll probably find that it doesn't change much after initial break in. I only mentioned keeping an eye on it, because I got lazy (well, in all honesty, I was lazy all along) and it bit me right in the stage light. Set the trans brake and rolled backwards, redlighting. Wasn't much Kevlar left on the band. Also, I don't think the Kevlar is a must; the stock lining works pretty well in some applications.

What I meant by 'bracket stuff' was to differentiate from class cars that may be relatively heavy and running smaller engines with less stroke. Those are the cars that need the deeper gear in the P/G. I'm using an ATI straight cut 1.87 behind a 406" @ 3250 lbs. Kinda wish I'd gone with the 1.80

Ken, thanks for the info. I'll keep up on the band. Go the new tranny in last night. I cant wait to try it out but were getting a blizzard here on Long Island this weekend. I'll have to wait until warmer weather. This Vette with a 4 link should 60' at least mid high 1.30's
