Anyone know this? 5.7 into a 81 truck

I'm wondering if anyone around here would know what I need to do to put my 2008 5.7 hemi into my 1981 dodge crew cab? Referring to mounts. I'm pretty much completely researched out on everything else lol.

Also does anyone know how to make the NAG1 work? Cuda-Challenger has a guy who got one to work but He hasn't posted in a while now I've tried a couple different methods of contact and can't find the guy. a PCS controller seems to be the best candidate as they have a military application for the direct sibling of the NAG1.
