4k Stall? Who do you like?
4k Stall? Who do you like? I've kinda been out of the car game for a bit, but I still have my 2000 Trans Am and I'd like to breathe some new life into it.
Used to be a DD so I wanted to keep it mild - went with a Vig 2800 converter, TR224 with some TSP 2.5 heads and a rear end out of a stock 3.42 car. So that's how she sits right now, of course with all the accessory bolt ons for the heads/cam package.
It's no longer a DD, and sees less than 200 miles a year, if I'm lucky, but I want to change that and I'm thinking about a 4k converter to replace the Vig 2800.
I think the 4k would wake it up considerably and if I still feel like it needs more, I can go more aggressively on the cam.
When I got into this Yank and Vig were the only real game in town for a converter, but that was pushing 20 years ago. I'm sure that's changed quite a bit.
Who are the hot torque converter guys right now?

If you did then you would wanna be shifting at 7k+ with a huge cam and the 4L60 wont survive too many of those lol...

3.42-4.10 swap with a ~4k converter already in place would only be worth about 1-1.5 tenths of ET reduction, but ONLY with a very sticky tire. Not worth the hassles and cost of the gear swap IMO.
Honestly, beyond the converter swap I'm not really sure how the car could be "woken up" any further unless you wanted to do a big power FI build. You already have a decent heads/cam package with all supporting bolt-ons (so I'm assuming this includes LT headers, full exhaust, intake, etc.). The car should run well into the 11s with the converter swap and good tires, I don't personally consider that to be "sleepy" for a street car.
Forced induction or a big cube stroker crate package would be the only things to dramatically increase power.
I agree.

The car has never and likely will never hit the strip. I don’t street race it either, I just enjoy have a quickish vehicle.
Some things would seriously have to change for me to go stroker. Just too many other irons in the fire.I’ve considered a small, Sloppy Mechanics turbo but not enough to even go as far as to price it out.
I think going from the 2800 to the 4000 would be an obvious SOTP improvement.

You're right that Yank and Vigilante (Vig) were the big names for F-bodies back in the day, and while they are still around and respected, a few other shops have really stepped up and become industry leaders over the past several years.

FTI 4000 here. Very streetable. I suggest you get with the manufacturer and let them help you spec the converter. There are different factors that can make a big difference even with the same stall speed. And....if you are drag racing alot start saving for a bigger rear end. My 10 bolt bit the dust on the third pass on the 4000 converter.
