10" Torque converter recommendations

I run ATI in my Gremlin but its a 8" treemaster converter with 5200rpm stall
I love it....... Runs on the streets no problem and no temperature problems on the trans

Ive got an 8" but want to run this on the street 90% of the time

I'm no expert on stall converters, but I ran one for probably 25 years in a street car.
It was a 10 inch B&M Super HoleShot 3500 stall in a TF/TC 727 in a 343/360 AMX with 3.73's.
3500 stall seems to be kinda an "upper limit" for 10 inch converters.
The "drawback" is the internal mods done to get 3500 stall cause 5-7% or more SLIP at speed.
imho if looking for a 3000-3500 stall converter the smaller the converter diameter
the more efficient, less slippage, it will have at speed, like in street driving.
A good 8" or 9" 3200-3500 Stall Converter will cost $900 or $1k though.
My B&M converter was under $400, albeit over 25 years ago, and is still in the car.
But tach readings and trap speeds indicated the 5-7% top end converter slippage
which B&M confirmed as "normal" for what I had in phone conversations.
I really wanted to spend the $1000 and get a "good" 8 or 9-inch" converter because
the "math" showed the car "should" run 12.00 flat and it ran 12.6's with the B&M.

Yes I am going the custom route for sure...looks like an ATI treemaster at this point. Somewhere around 800 bucks so not cheap but good parts never are and I hate yanking transmissions back out. I have a 10" 727 TC laying on a shelf I got in a package deal but have no idea what it is and am not taking any chances. Gonna sell it and the 11" TCI breakaway as well

Have you checked out Turbo action? They make a bunch of stuff for our AMC's.  Got a custom made 10" steel stator converter for $800, that's not bad. But then again that was like 3 yrs., ago.
