Truck has a 4L80E behind a 6.0L that makes 500+ rwhp. 3.73 rear. Recommendation from a guy who's opinion I respect tremendously said go with a Yank 2600. I was shocked, putting it mildly, to find out the converter sells for $900 + shipping. Back in my younger days, $900 would buy a well built turbo 400 tranny with converter. Shooooot. Is there a less expensive way to accomplish what I'm after? Your thoughts appreciated.
Old school at this end also. Why change it? If it's not broke, don't fix it. I'm building a forged 6.0l and planning up turning up the boost to about 15psi. I'm going to run with a stock 4L80E converter.

I have had PI's and Yanks in my 60's and never had the first issue with either other than the PI being a hair too loose. I just picked up my new Circle-D 258mm 80E converter yesterday. And they do offer one that's not over $1K... But its not the multi-disk bad boy, its a single, after seeing the guts of the single disk I wouldn't be scared of it

All convertors for OD trannies seem expensive. They cost more if retaining the overdrive.
If you are running a stock 4L80E converter with 500WHP, I bet you are already seeing close to 2600 stall with the stock converter. I've ran into many posts with people running the stock 4L80E converter w/FI and getting great results and durability.

Just talked to Chris at Circle D. They do make a 2800 stall speed single disc converter that's quite a bit under $1k. He said as long as there wasn't a full throttle lock up, it would be fine. I'm guessing there is no lock up under full throttle? Maybe for a dyno run, but under normal circumstances, does the converter lock up under full throttle?
