Help me pick a torque converter

[pat]

I decided to replace my old converter with a new one while I have my engine pulled out again b/c I think it got a bunch of crap in it while it sat out for a year or so.
Im running a 383 with about 380 hp and 400 lb/ft torque, a rebuilt TH350 tranny, and 3.07 rear end. I dont really know what I want so any suggestions are welcome.

call tci and have all your specs ready.
engine size
tire size
cam spec sheet
rear end gear size
and maybe more
the higher the stall the high the trans temp. might want to look at trans coolers too if you don't have one yet

my pro-street truck run's two coolers one in front of the radiator and one behind the front bumper with a fan... 3800 rpm stall

Ok, Ill try and give them a call Monday. The trucks gonna be kind of a daily driver, not really built for racing, but thats not to say I dont want performance.

your rear gear is going to hut you. The problem is, you need the stall speed to be lower than your cruise RPM, which at 60 MPH, you're turning less than 2500 RPM with the 3.07, so you are rather limited.
With that being said.... I agree 100% with calling the converter tech lines. TCI has one, I think Art Carr has one too, pretty much all the big names.

Here you go.

Go stock,
I have run multiple applications using different stall converters, Longhorn is right about the gears. Look at all the cars the maufacturers have built with about the same power as your claiming and they all run stock converters, where as there maybe a slight variences between something like a truck (Busses, RV's, etc.) the bigger trucks might have a 600-800 stall where as the station wagon might have a 1000-1200 stall and usually most high performance factory cars 1200-1400. In my current rig with the same gears as I have had but different motor setups I have been running a 2500 stall, up untill my last couple configs 413, 427 with the current cam I would have been much happier with a stock converter or possibly somthing in the range of 1600-1800 stall. A stall coverter (2500) will not slip under a light load but if you getting into it at 1200rpm it will slip untill it reaches the intended RPM or flash which may be actually higher than what you would think. Both A friend and my rigs we run 2500 stalls, both these units flash at 3500rpm on the dyno. We both use TCI converters, he has a Furd pushing 400HP 390TQ and mine 392HP & 412TQ at the rear wheels. On a 400 horse engine you are like to see around 300HP at the rear wheels, 350 Turbo 20%, standard trans 15%, turbo 400/700R4 25%, 4wd more, driveline loss.

I did have a 1900 stall unit in my old GMC, it flashed at about 2200, the improvement was invisable onless you floored it.
None the less... call B&M or some one.
