MMX has new 6.4 long blocks that you can even spec with an upgraded cam if you want,that are fairly reasonable in price.

I’ve been eyeballing the junkyard. I have a co parts here that gets newer vehicles through for auction occasionally and I’ve seen a few high mileage 6.4 ram tow trucks or work truck models on the roster. I wouldn’t mind having honed and cleaned with all new bearings. That would be great too because I could sell the 6.4 heads off to recoup some money and reuse my 5.7 heads to bump up the compression from 9.5 to 10

Swapping engines is cheating (I say after spending way too much on my 5.7)

Have you considered either a 411 or 422 Khris,they're actually a fairly reasonable buy for what all you get in them parts wise
