I've been thinking about ways to convert the engine in my 96 cheyenne pickup it has a 350 in it right now, but I would love to drop a 572 in it. Is this a good idea, or am I just crazy???

I'm just horespower crazy, and yea it does cost a lot of money, but I really wanted to know more about the engine.

if the p/u is totally original, keep it that way it will be worth more. If it has already been modified it's as good as any other engine, but remember, if it's running fine right now, save your money for a bigger better project because you might make a big mess out of it and have to junk it all..

Long Answer: Well, first of all, you're looking at $8-14,000, so you need to first consider if you're willing to spend that on JUST AN ENGINE.
If you're going to be doing the labor yourself, you may save some money, but in the end, I think you're looking at $20k here. I mean, it's a big motor, and a '96 may not (probably won't) fit that beast. Then, you need to consider whether or not the transmission will hook up with it or not. Even if the bellhousing does manage to fit (I don't think it will without fabrication) you're going to need to toss the guts out of it and either rebuild the heck out of it or buy a whole new tranny...not too many stock transmissions can handle 600-750hp. So, even with the rebuild, you're looking at another grand probably, but with a whole new tranny, you'll probably be looking at another $5,000...the transmission, a new crossmember, the fabrication that may be required to make it fit, a new driveshaft and some new rear-end guts and axles--again, to handle the horsepower.
Most likely, you will also have to move things around in the engine compartment, and you may even run into suspension problems because of engine clearance as well as added weight.
This hasn't even considered the wiring yet. You will need to rewire the engine as well as pick-up a new ECU to work with the new engine and transmission. I don't think this will be a simple re-programming either.
You want to do a rebuild? Lookey here...

This is a magazine where the last issue (September or October of '06) covered a story where they sent 3 teams out to build nasty street motors without spending over $5,500. It's a good magazine in general, but this is right up your alley. One of them (maybe more) was a 383ci Stroker...a motor with a longer stroke for increased torque. I think they may have even managed some 4-600hp numbers. So now, you've got it all wrapped up in a neat little bow.
First, the engines in the magazine come with complete build specs and dyno numbers...even pricing for all of the parts. Second, you can build a Stroker out of your 350 (provided it's not shot to heck) or you can just buy them from Summit Racing. Finally, with a 383 Stoker or even just a juiced up 350, there won't be any need to replace the transmission. If you're going to pump anything more than 400hp through it though, you should definitely get a stout rebuild.
Save yourself the money, and skip the 572. It's more for high performance racing applications anyways. Stick to the small blocks, and use that saved up money for upgrading them.

JDM is right the 572 is reseverd for the rich with nothing better to spend money on. a properly rebuilt 350 or stroker will be enough to make you happy but dont go over board or a tranny up grade will be needed here to

It would be a terrible idea. Cadillac had the 572 many years ago and was not a real good motor. How is the computer system swap going to work?
