I would run at the least a 2800. Had a prostreet S-10 with a wicked 355 and ran a 3200. Wasn't too bad. Caught hell when it rained though, LOL. Poor bf goodrich tires.

Depends on what you're willing to spend. A good 3500+ converter that will work on the street can be had, but they are expensive. I have two vehicles with 3500 stall 9.5" diameter single-disc L/U Precision Vigilantes. Both are street driven and very well mannered. These converters in single-disc L/U are about $750. In contrast, I've tried running a stock diameter 12" restalled to 3000 and it was a ($300) joke.

Have you actually weighed this car? Unless it's a tube chassis with a lot of fiberglass and aluminum, I'd bet it's probably closer to 2900,
Not that it makes a lot of difference, but I've owned some Vegas myself, small block and big block, and none were that light,

You have two different situations posted there.

Flash stall RPM and stall RPM are different , different method of operation of a converter.

A converter may stall against the brakes at 2500, yet it may flash to 2800 RPM when properly operated.

A flash stall is obtained by holding the car with the brakes , bring the throttle up to a RPM where the camshaft lope is mostly cleared. Then hammer the throttle as you release the brakes ...for a short moment the converter will flash to a higher RPM than it would by simply hold the brakes and stab the throttle.

If the tires spin when flash stall is attempted , then you have a false RPM indicated

I've worked for Hughes for over 11 years, so my opinion is a bit biased

If the two you are referring to are TCI and B&M then I would say "other". Their street line of converters are closer to the joke catagory than the quality side. This is one of the bad areas to get cheap, good rule of thumb given to me for converters in this range(2800-4500 stall, 9-9.5-10" diameter) is that if you are not spending $450 you are getting a compromise part, just the necessary parts to assemble the converter alone cost $300+. Anything cheap has corners cut in the converters construction.

I'd say 3000-3200 stall in your case, 3600-3800 if you really want to "tear it up" at the track..

I can add JW Performance to that list, I know you've heard of them, they make the Ultra Bell, and they build some first class converters. www.racewithjw.com ,
