What's a good torque converter to use in an IMCA Hobby Stock with a powerglide?

Superdave, This is a good question, I've been waiting for the answer. What I did was buy a rebuilt stock one, the only problem is it's big about 13" diameter and heavy. Everybody wants to sell an expensive aftermarket piece. I'm told the vega one won't hold up even if you can find one. I'd like to know if there is something better than what i've got. Is one out of like a 6 cylinder nova smaller? Sorry I'm not more help..loojack

For IMCA the converter has to be OEM so I thought someone would know a smaller unit that would work with a Powerglide.

Daco has a rebuilt unit you can buy it only cost about 40 bucks dealer to a trans shop I dont know what they would charge for it but they call it a B7 and its about 1800 to 2000 stall and works real good if you can run a turbo convertor hope this helps....towman

The only problem with a stock replacement converter is the percent of slippage when the converter is above the stall speed, this is usually 8-10%, but could be more. When have an 11" converter that is a lo stall circle track converter. It has only 1-2% slippage above its stall speed and only stalls 1800rpm. Just enough to let it idle in gear. It is also built with Needle bearings to cut down on the internal drag and increases the life of the converter.

Is it stock appearing and about the same size? I know the little ones with the steel block legs won't pass tech. How about a picture?

Thanks,

superdave, After trial and error I came up with a solution for the powerglide trans where you have to run a convertor. install a dual ring servo and kevlar band., use a stock convertor, and use a spud type valve body. You will still have SOME stall and No slip!perfectly legal!

Johnnyb, What is a spud type valve body? Also the slippage in a powerglide is all in the converter unless you are running a direct coupler and then it only slips when starting to move. With the proper pump pressure a kevlar band and dual ring servo is probably not needed. Superdave As far as converters a low stall 11" is a good choice, call Mike at Precision Powerglides he can fix you up. 585-738-9166
