Has any one ever heard of a crank breaking? Thinking of doing a 6.0 swap!

I've done it in other vehicles but never a VX. If you don't have the mechanical aptitude to do it yourself or have the money to pay someone to do it, I would just find another 3.5 because it will get expensive. You would want to change out the transmission/transfercase (the 4L30E won't work OR standup behind a 6.0), you'll need to weld in engine mounts, modify or make a transmission crossmember, new driveshafts, not sure if the radiator can stay in the stock spot or needs to be moved forward (have you gotten to this point yet Ascinder?), you'd need electric fans for sure (good ones!), then all the wiring, exhaust work, running new AC and power steering lines, and the list goes on. It's pretty intensive when you do it in something that never had that style or similar engine in it. Was your engine making any noise prior to this? It'd be weird if it just all of a sudden blew up without warning.

The 6.0 will fit, but you will likely need to convert it over to the corvette accessory drives since this nets a couple critical inches in the fore/aft dimension. The accessory drive swap is not cheap to do, although it is bolt on. You will likely need to cut out a lot of brackets and such as well for fitment. I also ran the corvette batwing oilpan so the engine is able to sit lower in the bay if necessary. My current concern with my swap is if the shorty headers I have will clear the framerails. If they don't then you'd be advised to go with some power robbing block huggers. You will also likely have to contact your local DMV and see what they say about engine swaps. Some people have issues there. You can also change the intake manifold over to the car style which gives a couple more inches vertical. In my opinion, the 5.7 LS1 or LS6 would be better initial choices since just about everything about them is the same as the 6.0 except they're aluminum and a little more compact and easy to package. They are however more expensive. You can pick up 5.3's all day long practically for free though, so don't rule them out either. With the money you save on the engine, you can more than compensate with power add ons. Everything pretty much bolts up to everything else on this family of engines.

Or if you want aluminum AND cheap, the LM4 5.3 is all aluminum and can be had fairly cheap (under $1000 complete, still alot cheaper than LS1/6 or LS2's). Check out LS1tech.com or performancetrucks.net, the classifieds section over there is nice and can save some dough on different parts. Dimensionally the long blocks are all the same and the LSx series of engines are awesome and a breeze to work on.
