On my 95 Firehawk I plan on doing Headers, 3.73 gears, shift kit, and maybe some Rockers ( if it is worth it). I was asking around last night what size converter for a bolt on car and so far I am looking at around a 3200 stall. Anyone have any other suggestions? This is the 2nd Auto F-body I have owned and the 1st in 6 years. Its a fun car but I think adding a stall will wake it up a bit and make it a little more fun to drive as well!!

I would say 3600 stall in a LT1 or 3800 stall in a LS1

If you DD it, I would stay under a 3200 stall... your wallet will thank you...

I run a 3200-3400 stall with 3.73s and cruising on the highway, is, painful...

I would call a number of converter manufacturers and see what they say. They would know the best.

And to add to WBT, JSperf is a precision dealer, he can hook you up with a good verter specced for your car.

Just make sure the converter you get can lock up, that saves the highway problem

You could have a torque converter custom made to your specs. If you are really concerned about drive ability, I think you should contact Yank, Precision Industries, or Circle D and see what they recommend.

I ran a 4000 vigilante in my bolt on LS1 for a while, it was very loose. Needed like 2500 rpm for normal acceleration, but still very tolerable.

I will say my next converter will be tighter it got kind of annoying since I dailied that car

JS Performance will do a custom stalled Vigilante Converter for you based on your needs. Dont skimp on a cheaper converter because drivability will be affected. My car drives nicely despite the work done to it.

It is not a daily driver. We drive the WS6 and Firehawk pretty much on the weekends if at all.

Thanks for the replies everyone.

I drove 2 stalled F-bodies and they both had a 4400 stall and heads and cam. I had a blast with the stall. I plan on keeping the LT1 pretty much stock with bolt ons.

Ive had 4 different PI converters
2800, 3200, 3400, 3600. Couldnt feel much of a difference between the 2800 and 3600.
and a 2800 stall pro torque
my 2800 stall pro torque felt just like the 3600 PI.

Matt... do you know what a lock up converter does? your stall speed doesn't effect your MPG at highway speeds because the converter is locked
