Currently the class we run requires the GM rear housing. Due to this fact we have to gear using 1st. 2nd is not even installed. If your running a 9" you can gear for 2nd, if it's in your budget that's what I recommend.

If I were to use the glide that I have I would run the car in high gear. Eddie

If ur running a Ford 9 then run in high that way you can use the 1:1 with your gear in the rear.

If you choose to run it in first then just remember 1st gear is a 1.72.

I've always heard that Powerglides from V8 cars had 1.76 first gear and 6 cylinder units had 1.82 first.

I've had pretty good luck running in first gear, but remember that you are running off the low gear band and not the high gear clutch disks. Try to stay on top of band adjustment because the trans will slip at high RPM if the band is adjusted too loose or the band is worn too much. Also, I'd run a trans cooler if you're using first gear.

Yaz, I have been running a PG in low gear for 4 years now and have beat many guys running T350's and 3 speeds. I only blew one up once in that time. I have a GM 10 bolt rear with 3.42 gears and a 1.76 PG. It's a lot easier to find the right rear gear with this setup. Use a trans cooler and change fluid and filter regularly. I will definately stick with running in low gear.

I run a 1.76 PG with a 3.73 10 bolt. I run in low and I use a tranny cooler on the firewall. I'm going to either move the cooler or put a fan on it this year to get a bit more cooling. I'd like to put the 9" in, but I just can't afford it. Plus, 6.80 is a really pricey gear to find and if I went to the 9", that's what I'd run. Most of the high dollar guys are running 6.80's in 2nd with their 9" at my track.

A little known fact is that the 9" Ford rearend actually burns up a few more horsepower than a Chevy rearend does. The Fords are very strong, but at a cost of 1. additional weight (unsprung weight too!) and 2. more gear mesh which equals more friction and associated loss in horse power. Going to all the trouble to install a 9" rearend just so you don't have to run low in a Powerglide is probably not going to net you much differnce in speed. Might be worth it if you were switching to a lightened 2 speed standard or a direct drive racing tranmission, but if you are keeping the 'glide, I don't think it's worth all the work and expense.

Why the 9" convertion? Are gears unavailable for the GM rearend?

Fords are stronger and you cant fit much more than a 5.13 in a GM rear end.

GM rearends don't have as many ring and pinion choices as the Ford 9". Tallest gear available:

8.5" 10 bolt = 5.57
8.2" 10 bolt = 5.13
7.5" metric = 4.56
12 bolt = 6.14
