Right Stall converter??
I know you're supposed to base the stall convert off the CAM. Thats where my problem comes into play. I bought the engine used so i have no cam card or cam sticker, and i have no idea what cam it could be
I do know it is a Comp Cams. And there is a sticker on one valve cover with 10 part numbers and an executive order number(D-279-6) It supposedly is a 383 stroker motor. Ive narrowed it down to about 5 different cams it could possibly be 12-207-2 duration: 255/261 lift: .421/.451 050: 203/212 12-208-2 duration: 265/269 lift: .442/.465 050: 211/221 12-206-2 duration: 260/260 lift: .440/.440 050 212/212 12-210-2 duration: 268/268 lift: .454/.454 050: 218/218 Now this one has a higher lift, so if it was a stroker motor maybe this one?: 12-106-3 duration: 342/342 lift: .447/.447 050: 222/222 Any ideas?? How can find out what cam i have? Are those numbers different enough to make much of difference in choosing stall converters

Re: Right Stall converter??
i would probably not go over 3000 on the stall, my cam looks to be bigger than that and that's all i'm running and it works fine

Re: Right Stall converter??
If it is a mildly built 383, my money is on the 210-2 cam (268) With 268 NOT being the lift, but the duration at .050.
Run a heavy duty stock convertor unless your going to romp on it all the time. What's the rear gear ratio?, tire size? |

Re: Right Stall converter??
I would go on the side of caution and say 2400 to 2600. If you have a low rear gear lean more toward the 2600 side. If you do go with much over a stock stall and you drive in traffic a cooler at least and a cooler with a fan would be a good idea to keep the trans temp down. Also a deeper pan so you can have more fluid[more fluid=more cooling] and a trans temp gauge are not badideas either. Jim

Re: Right Stall converter??
Might just want to stop guessing. It is an unknown used engine. Pull the pan to look at the bottom end, oil pump and verify it is a stroker. Pull the timing gear to verify the cam numbers. Sticker could have come from anywhere.

Re: Right Stall converter??
going through this now with my converter, mine is being built or if you call TCI/B&M etc. the more info you can give them the better.
cam duration and lift @.50 truck weight rear gear tire size engine hp @ flywheel what are you doing with it, street/strip, towing. track etc. A long time ago I R&R'd transmissions for a little while and asked the builders a ton of questions. The more info you can give them the better. I have seen plenty of overstalled converters kill the performance of a good engine. I personally don't like to guess. I would verify what I could.

Re: Right Stall converter??
What are you using the rig for? Make sure you know what you are getting into if you are looking at a 3,000 stall on the street.

Re: Right Stall converter??
Yup... If you're towing and hauling... that 3,000 stall will make a lot of extra heat in the tranny.

Re: Right Stall converter??
I dont want to race it or anything like that. I just basically want it to be a cruiser, i dont plan on towing much with it but i'd like to have the capability if need be.
I have pretty good size tires on 15x8 rims. I believe the gear ratio is 4.11 but i eventually want to swap out the rear end with a ford and 3.73 gears unless the 4.11 are better for cruising and overdrive. I want to be able to have pretty decent take off capability but then again i'm not gonna be racing it.

Re: Right Stall converter??
With 4:11 or 3:73 you'll have plenty of take off with that 383, they are torque monsters

Re: Right Stall converter??
Any of the cams listed, will be mild in a 383. Your stock converter will work just fine.
