Howdy All,

Needed to Join forum due to project. And I Thank ya all for all the information you have posted. PROJECT - 1992 C3500 original 5.7 NV4500 combo. - Swapping to a 7.4 NV4500 combo.. Just need more torque for the old girl(Dump Truck). Current ECM (5.7) 1228747 - Want to swap in the 7.4 but I have a 16147060 ECM - from RV I guess the 4l80e tranny.. I was going to look at the diagrams and determine if I could just plug in the 7060 or do I need to find the prom for a 8747.. I have all kinds of projects and i'm sure i'd bore ya with those..

I'll post something more formal if I am unable to find the info I need, but if you went through the same setup or know what I need, please don't hesitate to comment!!

Thanks in advance
