I've got the 5.7 and would like to swap in the 8.1. Does anyone see any problems? I should think the stock ECU would work...:4-dontknow:

Apparently the new 392 is based/more related to the 09+ 5.7 than the 6.1, which sucks because the 6.1 is a much herkier block. My long term plan is to build a nice 6.1 based stroker hooked to an ATS 545RFE (someday).
