Like David mentioned, you get what you pay for. The cheap gearsets do and will break. The stock 1.76 gear will break and it is just a matter of when. You might run it for 2 years and you may break it in 2 weeks. The cost of pulling and replacing the gear set and the potential race winnings that it may cost you are worth the initial investment up front. I see a lot of people not want to spend the money on the transmission and it costs them twice as much to replace and repair what can break in a transmission failure.

Heres some FOOD for Thought,...........?
A good freind of mind that just moved south to Ark.,built a Brand New Altered,SBC Injected 406 car ran desent,5.50-.060's.He had (STOCK)Planetary in the Glide.Well last sat.He TOTALED the B/New Car!
He was Bracket Racing,had the Guy covered,hit the Brakes HARD!The Planetary EXPLODID!The Car is JUNK,He barrel rolled a few times and I thing Enddoed also!
So,....?He spent ALOT of $$$ in the WRONG Place,.....???Get what I'm Say'ing?
The AFTERMARKET Planetary is a SAFETY Feature,that as far as I'm concered,ANY Car Faster than say 6.00 in the 1/8,9.00 in the 1/4,SHOULD BE MANDETORY!!!!
I'LL BET you have ALOT MORE in that Upper End!!!!

What
The reason a Powerglide works well is because it does not have a low gear like a Turbo 400. The lack of gear multiplication makes the converter multiply torque better and results in a faster car most times.
Rear end gear ratio and tire diameter will make more difference than trans ratio.
1.80 works more times than not even on a small block if the proper converter is used.
Look at all the transmissions for sale on this site and you will see few lower than 1.80.
