My torque converter is going to get fixed, and I wanted to get ready the info I want to send the company for what kind of coverter I want. If I could get some feedback from some people on it...
The shop that did my cam swap & dyno reccomended something that is kinda loose down low (he used the word slimy), but that bit around 3000 or 3200, so it idles fine and doesn't shift wicked hard but isn't going to be terribly inefficent. He said the converter I had is a little too loose and sloppy for him, which was supposed to be about 3400-3600 stall behind a motor w/ 25 less ft-lbs and 25 less hp.

Here is a quick rundown of the car:

4020lbs w/ driver and 1/3 tank gas
462 (+.032 454)
performer RPM
holley 4779-6 750 w/ 850 baseplate 72 78 jets
solid roller 287/291 256/260 .643 112LS
2" primary headers (a little big I know..)
3" exhaust w/ x pipe, mufflers and tailpipes
TH400 w/ OD unit
12 bolt w/ 3.90s

and here is the dyno sheet from the shop, unfortunatley it is one of the pulls starting @ 3400 instead of 3000. Dyno pull is w/ 88* deg room temp, 38* timing, mobil 93, my headers, my exhaust, my mufflers, alternator and water pump.

tq @ 3400 537
pk tq @ 4400 553
tq @ 5900 500
tq @ 6200 473
(6200 is max recommended operating RPM)
hp @ 3400 348
hp @ 4400 463
hp @ 5000 521
hp pk @ 5800 565
hp @ 6200 558

use of the car is limited miles during the summer (a few thousand usually)
occasional (4x a year) strip visits
the new solid roller is actually a little more pleasant to drive (although I suspect that could be just from the quietness of the x pipe) than the much smaller hydraulic roller (go figure) but can't operate my power brakes at idle (1k rpm). makes for scary pulling into my garage.

I realize I should have stuck this in transmissions now, but I am sending the converter out tomorrow and wanted to know if everyone thought that what I have above sounds like a good idea for me.

Matt, the difference between a 3200 converter and a 4200 converter in an 11 second combination I had was about .4 in ET.

The 3200 will be a Lot nicer and quieter on the street but a little slower off the line at the track. Your cam is pretty aggresive with a little more duration than I run in my 540 and will work best with a 4200 to 4400 flash converter at the strip.

Matt,

Tom pretty much hit the nail on the head. For a pure streeter 3000-3200 stall. For best times at the track around 4200-4400 stall.

Thanks guys. I don't know if I could deal with a 4000+ rpm converter on the street or not. I'll just get mine inspected and fixed if thats the case.
Although the car is so much quieter now, I suppose...

4400 is what you need IMO for the quickest running car. Any lower and it will not be into the sweet spot of the torque curve.
