Is there a formula or something for ideally matching the stall convertor with the motor or cam? I have a 72 GMC that I just put a rebuilt 355 in. Now, the trans TH350, is starting to slip while in "D". I plan on using this truck to pull my 66 Chevelle. The 355 has 9:1 comp., .465 lift 224 duration, Holley 600, Weiand 8007 dual plane aluminum intake, small headers, 3.07 posi rear. The truck is a cruiser, and a tow vehicle for the Chevelle. I am going to get the trans rebuilt soon, and install a shift kit. What stall should I purchase for it? Thanks!!

I'm not sure that I'd want a stall converter on a tow vehicle,gonna get hot enuff as it is towing the car.

Every converter is a 'stall' converter, some just stall higher than others.

I believe B&M has a "torqer" stall converter, I just don't recall the name. Anyway, if memory serves me right, it was meant for tow vehicles. Could be what your looking for.

i would rather not have a higher stall in a tow truck of sort.......there are some tow truck stalls that rate as low as 1200 rpms...most stock stall that i have came across have been 1600-1800 rpms .....doing the "brake stall test".....personaly the 224 cam you have now is alittle big for a tow truck.....i would have went smaller, but no bigger then something like 204 214 range.....but since you have what you have.....i think i would just stick to a regular new convertor that would stall somewhere between 1600-1800......

i'm going to be building a "tow" truck here shortly using a 454 and im going to run a cam in the 200 to 210 range split duration cam with a 1200 stall made for towing......

make sure you add a nice big tranny cooler to your rebuild........heat kills the tranny......cooler the tranny the better life it will have.........and i would say no big stalls are needed.........

it would be a different story if the truck was built just for performance then i might go with a 2100 stall with that cam......jmo

Great article.

I know a torque convertor is a stall convertor. I was just curious as to how high a stall speed to go since it will also be a tow vehicle. What's stock, about 1200rpm, maybe. I was hoping to get something a little higher than stock. But not too high. So a 1400 to 1800rpm would be good?
