Just picked up a 2004r transmission for my 86 cutlass supreme im going to rebuild and upgrade it but not sure if Its possible to use a stall converter with a lockup trans and not sure how big of stall to go with if possible
You want a 2500 stall with that cam and at least a 3.42, probably a 3.73 is better depending on the tire size. That will be night and day different.Duration 268/280, Lift .485/.490 and currently has 2.29 gears due to currently having 3 speed but will be switching it out just not sure what gears to switch to mostly going to be a cruiser
This is pretty good advice but word of warning, do not cheap out on the stall converter. You’ll be sorry. A cheap converter Includes brands like B&M, Summit, etc. and they’re nothing more than the factory converters that they took apart, modified and welded back together .Cheap converters will be too loose and are very annoying when driving around town. A good quality converter like Circle D will drive like a normal car until you put your foot into it.You want a 2500 stall with that cam and at least a 3.42, probably a 3.73 is better depending on the tire size.

Agree my $200 2200 to 2500 stall PATC, flashes around 2350, it is Ok but has about 10% slippage when not locked up. Everyone really likes the PTC "Dr Dan" 2800 stall for the 2004R. Dr Dan Mascal, knows the 2004R, he builds them into the 9's in the 1/4. It was only around $450 last I checked. Like L92 pointed out, like a stock converter till you step on it. I had an Oregon Performance 2000 to 2600 stall, flashed around 2400 and was loose, implode running the 1/8 mile. Then it was like a sling shot, just getting home.This is pretty good advice but word of warning, do not cheap out on the stall converter. You’ll be sorry.
