Which stall for this combo.....

I agree give Lenny at Ultimate converter a call he's the "best" in the business and i'd go with 3.91's or 4.10's!!
On the converter… Best advice given right here ^^^
and the only one I’d pay attention to and Lenny is a great guy and awesome with this stuff.

Your going to have to make a choice here…
Mainly, your combo is off balance.
IF your going to stick with a 26” tire and 3.55’s that are more for the street, your going to have a very different converter for 4.10’s and 28” tires.
IMO, you have a pretty stout street cam with no where near enough gear even with 26” tires. Which are small, and normally helps in some areas. Not here today. The engine is going to make enough power to shred them under WOT.

I think everyone above is on target with 4.10’s and 28” diameter tires.
