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:

Thats a 6.4L. They make crate engines with aftermarket ecm's as a swap plug and play. They have normal hemis all the way up to a "440 hemi" that makes like 650hp. Its bouchillion performance i think? Just google it
