I had a similar combo and in less than 500 miles the converter came apart. when i pulled the converter off the trans the sprag was in 3 pieces stuck on the input shaft. pretty much destroyed the trans. If that is the case, go with a 2800 stall when you go back together with it. good luck with it all.

Here is a link for the engine (with dyno specs)http://www.blueprintengines.com/popu...specs&pc_id=67.
The cam is
.487Int / .508 Exh & 234 Int / 244 Exh duration @ .050 - 112 degree lobe sep.

Stock the VIN says it has 373's with a TH350. I had the trans redone and had the add a **** kit. I'm going to keep an eye on it. If it gets any worse I'll take it back and have them upgrade the stall. But I really don't want to go over a 2200 stall. I'll be towing a boat and camper (popup) with it.
