need converter stall suggestion.

I can attest to all of that! And I would use caution with Dynamic converters. Their advertised "stall" speeds on their website are way, way off. Mancini racing advertises more accurate specs for the Dynamic products.
Lenny at Ultimate will be away due to emergency until late the week of may 19th. Len is VERY detail oriented. Good luck with your converter

Your converter should be custom taylored to your car anyway. Off the shelf units of any kind are a hit and miss. 4.10 and 3.23 will stall at totally different levels, weight, hp, torque, etc, etc...too many variables

I wanted mine to stall at 3500, mine will footbrake to that, and flash at 3900 just like i wanted it. Ordered it straight from Dynamic, took down all my car's specs and tweaked it
