NOT the electric version (the hyd version has 1 pin or 3 pins on the electric plug, not the NSS plug).. then change out the input shaft so you can use a high stall conv... if guys are using the lock up version they put a spacer behind the engine so they can put a thicker conv in.. the conv with a decent stall and lock up cost about $1800 and up EDIT you need too change the pump gears or the pump assm to match the 727 conv if you go non lock up Last edited by MR_P_BODY; 07/24/14 08:48 PM.

The truck trans are decent to about 500hp but overall they suck. PCS just came out with standalone NAG1 ecu. The only reason you don't see more nag1 swaps is because of lack of controllers. Mopar to the bone!!!

Street use is fine. The 545 comes in with a dry weight of a 175lbs and the 722.6 right around the same weight as a 727. I run a 545 in my truck and rebuild it every 100 passes or if and when the clutches burn up before that. Last edited by hemidup; 07/27/14 05:46 PM. Jerry Williams.

I know the OD and tail shaft assembly feel pretty heavy

I know the OD and tail shaft assembly feel pretty heavy I took a bare 727, 904, 833 iron case, T56 and a 722.6 and weighed them side by side a few years ago. If my memory serves me right the 722.6 was within a few pounds of the 727. + or - I can't remember but I do believe heavier and a 115lbs rings a bell but I'd have to check my old notes to be sure. My memory just has to remember where I put them now. Jerry Williams.

He couldn't even get home from the transmission shop without toasting something in the transmission. It put down something like 500hp at the wheels with a Procharger and other mods. He ended up taking the supercharger off just so he could drive the truck without breaking it.
