I want to replace the stock converter. N/A car SCT tune for 91 with 4.10, any suggestion would be greatly appreciated.

Thanks

I was pretty happy with the budget circle d when I still ran the 4.6/4r setup. But that was like 5+yrs ago. So I'm not sure if it's the same now vs then. Good convertor is worth spending the money on.

I had used a oe style one in a previous vehicle that I purchased from transtar. I don't recall the manufacturer. But it blew up internally and wiped out my transmission a thousand miles after a complete and thorough rebuild. Sucks spending that $ twice.

I have had a Precision Industries for 180+ miles and 225+ 1/4 Runs. 3,000-3,500 stall. As respects a High stall it's all in the Tune.

I highly recommend a 4k stall

Can't go wrong with a Circle D. It was the direction I was headed til my auto died

that sounds horrendous in a mild street driven car. I hated the 3500 stall converter in my friends 96 impala SS.

thats a completely different vehicle and engine

The pcm in the marauder is capable of dithering the converter so unless your in the throttle there is no possible way to tell the difference between a 4k stall and a stock converter it will drive 100% identical when calibrated correctly.

2800-3k from MartyO is what I have with 4.10s. I like it a lot. Fine for daily driving great for racing.

It's very mixed, I was expecting something more straight :depress:

Most here get a 3k stall. Precision Industries, Circle D, or one from Marty. There's not much more to say on this.

I have the 3k Circle D with my mods, per MartyO's recommendation. Right on target IMO.
