Hey guys, me again. I am wondering what torque converter upgrades you fellas have done. Right now I have the stock unit in the car. I have heard guys from CVN putting upwards of 3200 rpm units in their cars. I spoke to a guy at Mo's Speed Shop and he recommended 2500. Something about how "these heavier cars stall at higher speeds."
I ask you guys, well, because once the new engine is in the car, it's going to be kind of a poor man's Marauder.

I miss whitey here
These mod motors sweet spot is 3500 and higher. Putting a high stall converter gets the engine to its peak horsepower ASAP and your off
Even a NA marauder motor would benefit from adding a 3500 stall, 60 foots would drop drastically at the track
Even with a 3000-3500 stall, with normal driving, the engine will rev higher than a stock converter, but it's not going to be 3000-3500 at light pedal driving, it'll be like 2000-2500 depends on converter
I daily drove a precision industries 3800 stall in a turbo regal, car still got 20 plus mpg and was fun fun fun at stop lights. Once locked up on the highway it was like a stock converter
Get a 3000-3500. Enjoy it

The Original Hellcat.
I've got a P.I. 3000 but if I had it to do again I think I'd go with a 3500.
I'd do a 3500 especially if you don't have 4.10's. but if you're not used to a high stall converter on the street it might take some getting used to.
I love the instant into the power range feel.
(just sayin).

Hmmm All good suggestions, but I am HIGHLY doubtful I'll ever see a drag strip.
