i'm in the process of building my first hobby, i haven't been able to decide what type of tranny to run. i can get a powerglide cheap, where as if i go manual, it will be alot more expensive, plus finding a good tranny. any opinions would be appreciated. thanks

Hi,In my experience in order to run an automatic you must have low gears in the rear, lower than most cars come stock with. I have found 3spd standards for $50.00 all day. I run a 4spd saginaw(it was free) in second gear with a 3.42:1 rear, on a 3/8 med bank I wont exceed 6500 rpm. I have formulas to figure desired gear ratios and RPMs. And some tranny ratios.
Good luck

i figured i would have to some good gears, but the track i will run mostly is a 1/2 mile. i know alot of guys that that at this track run 4.56-5.00's, but mostly with manuals
thanks for the advice

manual is more reliable in my opinion sure it might be a lot more to begin with but in the long run the cases don't crack as ez they don't leak fluid and are not effected by heat as much as an auto. you don't have to change fluid all the time or filters and if you have a starter problem you can always be push started and like 44 said 3 speeds are all over and cheap. as for the gears if you have a 9 inch rear end you can get any gears you might need to run in hi gear

If you can get a Powerglide cheap run it. No clutch to install or worry about. A properly installed and cared for (change oil\filter every 10-12 races)Glide should last several seasons in a hobby stock. also chevy gears come in ratios from 2.19-4.56 a hobby stock on a half gearing may be in the 5-6 range so with a 1.82 glide you would need 2.73-3.43 or so gears.

Hello, other than reliability, which has more horsepower, a powerglide or a 3 speed that has first removed and 2 and reverse lightened (saves 13lbs) and a 16 pound flywheel. Does one have more horsepower over the other, does one work better in corners? please help
