Which stall converter

664 Views 12 Replies 6 Participants Last post by  Pontiac_Maniac
I’ve narrowed it down to 2 stall converters. One is the ZL1 stall converter (2000-2400 stall). The other is the Circle D HP series 278mm 3000-3200 converter. I am getting a V1 BTR stage 2 LS3 NA cam. I have full bolt ons and 3.45 gears. Which one should I go with? I kind of care about drivability but performance is more important.
Thanks.

You can use stock with that cam but I think the best gains will be the 3200 rpm
Tatlk to the owner of Circle D, or any other option company. They can advise you best for what you need for your build and driving style, including where you drive regularly...
IN additional to what is mentioned above, driveability is greatly affected by the tune. Make sure you choose a reputable tuner.
Neither. The Circle-D 278mm and performance are mutually exclusive, and you will not be happy with the ZL1 converter. Your car will be an absolute slug out of the hole. I know several people that went with the Circle-D 278 converter and either PM'd me or asked me at the track what converter I was running because my 60' times were killing their's. All of them had the 278mm. Most if not all of them ended up selling their converters and buying Circle-D's 258mm billet converter like I was running. The ZL1 is fine for boost but not N/A. Definately spend the money and get a good converter.

For a daily, would single or triple disc be better? I went to order the 258mm 2800-3000 and it said single is “not available for 6L80”.
Have you had any luck calling companies like Circle-D, Coan, or others? They are the pros and can best recommend a product for what you want to do with the car and play nicely with other mods.

Yeah. I asked Circle D, BTR, and the performance shop I use. I’m getting a 3000-3200 258mm Circle D Pro Series triple disc.

Great! Glad you got some good advice and your build can progress! Any thoughts on plumbing in an additional trans cooler?

I have a cooler and a deep Camaro pan already. I might get a bigger cooler though.

Single or multi-disc depends on your power level. At your power level, a single disk is fine but it appears Circle-D is changing up its converter lineup. A triple disc would be overkill in your setup but it won't hurt driveability.

Yeah I had trouble finding a single so I just went with a triple. I’m glad it won’t hurt drivability. I just ordered it yesterday.
