Bail out on the V8 swap. It can't be done in three weeks (or even three years, apparently) so just get a rebuilt 6VE1 short block, an oil pan and some gaskets and have at it. Less than $2000 and a week of wrenching and you'll be rolling again!Originally Posted by stokes_osu
Hey - you asked!

There is absolutely no way in the world you're going to cram a V8 into a VX in three weeks, let alone before winter. Fwiw the 5.3 is the same size physically as the 5.7 or 6.0. The measurement I didn't like when I was speccing mine out was the depth front to rear. I fixed mine by swapping over to the corvette accessory layout which gives you a couple of valuable inches, but at a very hefty pricetag and a lot of scavenging(time). I also switched to the corvette "batwing" oil pan which has a much shallower, yet much wider sump so you lose some inches vertically. This let me sit the engine down lower to help with the center of gravity and allow me to run the much taller and more free flowing l92 truck manifold and still clear the hood. The problems you haven't even realized yet is that the stock transmission/transfer case aren't going to bolt right up to a V8, and won't even come close to holding up against one. Unless you have a fully outfitted shop, plenty, and I do mean plenty of down time, an unlimited budget, and an unnerving way of doing nothing but work on your VX nonstop for several months, then a V8 swap probably isn't for you. It takes so much more than people think that it isn't even funny. There is just no cheap, easy and quick swap out there for a V8.
The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself. Therefore all progress depends on me.
