Torque converter recommendation
The time has come to have the 700-R4 rebilt. While it's out I might as well replace the stock TC with a higher stall speed onet.
This vert. is a daily driver which I occasionally play with at the strip (best time : 13.5@102.7). I understand that a higher stall speed TC would help me to obtain my goal of getting out of the 13's into the 12's but I don't want to ruin the drivability.
What is the stock TC stall speed?
What stall speed should I purchase, keeping in mind my whife drives the car (and you know how they can be)?
Thanks,
C44EVER

I will tell you, that my 3200 vigilante is just as streetable as the stock one. But when you nail it from a dead stop, you can definately see the vig. shine, and the tires smoke :D
The best thing you could do to fing out what stall would be best for your setup, at the track is go to a dyno, and see where your max torque is at, then go ~500 RPM less with the stall speed. You will probably be around 2600-2800 stall speed. Then I would only buy a quality TC. This will keep drivability the same as stock.
Stall speed DOES NOT mean the car will not move till it reaches the stall. My car will start to move the instant I leave my foot off the brake, at idle. It just means that you are not at full lockup till that RPM stall.

I have a 3000 stall yank. To be honest I wish I had 2400-2600. At light throttle is seems the same as stock. But going 25-35 mph, and give it about half throttle, it stalls up, but dosnt move out as well as it did with the factory converter. At the strip it brought my 60 ft time down by about .25 seconds on street tires. they do help et. but as I said I wish I would have gone with a little less. With your L98 having more torque at lower rpms, I would suggest somewhere around 2000 rpm for a daily driver. But this is just my opinion.

Re: Torque converter recommendation (C44ever)
The stock speed is around 1300-1500 if i remember correctly. If this was a drag car, id say maybe a 2600 Vigilante or higher if its never gonna be daily driven.
But for good street manners, anywhere from 2000-2400 would be just fine and would cut some ET off. A shift kit and tranny cooler would also be a good idea to extend the life of the new tranny too. (a cooler would be a little more important if there are money considerations)

I have a Vigilante 2800 stall, it's great, with the 3.45 gears it gives me low 1.7 60' times.
Driving on the street, you'd never know the difference.

FWIW, I have the B&M Holeshot 2400 in my 86 MCSS, which has a 350 with LT1 spec cam, B&M 700R4. It turned out to be a great combo, very streetable with an awesome launch due to the MCSS stock rear of 3:73. With the lower 700R4 1st gear compared to the stock 2004R, it's like having 4:XX rear.
