So I have to ask, do you have a 572 laying around?

[DefEddie]

Yeah it's been done,but it was a twin turbo on a 4dr IIRC.
Passing emission's would totally depend on the state law's in question and how you did the swap.
As long as it retain's all emission's control's and is fuel injected then you should have no problem as long as the state allow's it and you keep track of your CARB and EOE? number's.

no, but i am thinkin about savin up for one. but on a school/work budget it would take a while. my tahoe is a father a son project, so its gonna take while to get it done. but i just got in a lowering kit and im upgrading my wheels and tires, breaks, and i just got it painted. (took the gold stripe off the bottom) so i was just wonderin if i could do it without much trouble (before i got my hopes up). by the time i get around to an engine up-grade they should have a good stock of used ones on ebay. lol. hey anyone got any pics of the truck that had the tt 572 stuffed in the 4dr? that must be a sick ride!

[Chuggs]

I could've sworn there was a silver and black two tone two door with a 572 featured in one of the magazines a while back.

[97'hoe350]

wat mag? ya know?

[Chuggs]

It took some digging, but I found the truck that I was thinking of. It was actually the cover truck on the June '99 issue of Truckin'. It's just like I remembered, black and silver with wicked graphics up the side, but unfortunately, it only had a 502 not a 572. If I had a scanner here, I'd post it, but I don't.

If I were you, I would forget saving up over $10,000 for a 572, at least I think they cost that. For an affordable big numbers powerplant, I would opt for the ls1 crate engine, I saw a few days ago that you can get one for under $4,000 now, and add 6 more grand to that puppy, and you would be well past your horsepower goals and probably have a better chance at passing emissions at the same time.

word on the 1200+hp 408 hehe

good point, but its just somthin about a huge big-block that makes the shivers go up my spine. and while im here, if i do it what tranny should i use? and should i box the frame?

[g9m3c]

Beefed up 4L80E. And the frame boxing depends on what your gunna be pushing torque-wise, any more than 450 to 500 ft. lbs. and I would definitely do some frame strengthening, whether that be boxing or adding an x-member or whatever. Sounds fun!

[97'hoe350]

ya, wen i do it. im still in school. quote from dad "you wont be doing that while that truck is in my name" or "you wont pass emitions with a big block crate engine" i am determined to prove him wrong on the emitions part. but also i plan on puttin push-button exhaust cut-outs on it. anyone done that? dont think i will ever be done with this thing, always comming up with new ideas for it. lol. and to chuggernaut dont worry about it dude. but it sounds like a kick ass truck. and in the engine bay, do ya think im gonna have any huge issues as far as space? i plan on tryin to lay frame on 22's (while keeping the 4wd functional) so im probably gonna be tubbin the front inner fenders. so i dont know if it will fit

[DefEddie]

If you lay frame on 22's in a 4wd OBS with a 572 in it then I will drive across the country to see that bad ride.
Not that it can't be done,but you can jack the price wayyy up.
Lowering a 4x4 and retaining a good geometry isn't really a problem,but bagging a 4wd and keeping it functional use's part's of the frame that would be taken up by motor I think.
Not that it can't be done,just saying it will be a huge project and I would definatly not want it to be my first large project.
If you decide to do it definatly post up build info and stuff,I'd love to see one if there isn't one already.
I like a more functional ride,if I had that I sure wouldn't be driving it much. If I did I would hate to take advantage of the torque.
The entire truck would need stripped and reengineered probably to do it right and actually utilize the power.
Sound's like fun,now I want someone to do it.

My advice to a new trucker would be to start slow and when someone tell's you not to do something then either don't or educate yourself completely in your decision. I would start slow,like first maybe mod what you already have while keeping what you want in mind. You can build it slowly over time,and do big thing's after you get another vehicle to drive.
Trust me,for the big stuff don't fool yourself into thinking it will get done in a weekend unless your really good and have really good friend's.

[97'hoe350]

i agree. with you totally. im not gonna be doing this for a little while (i am broke ) at least untill im 18 and moved out. this truck will be a life-long project for me and my dad. but the reason behind the madness is, well, to be the only one out there that has done it. i love looking at cars and trucks and wondering "how the hell did they pull that off?!" and also to prove to all that say i can't that i did. finally i want it to be the "ultimate" nothing less. man i have high standards. lol. i think that you will end up driving across the country my friend, to see the badest tahoe in the world. but that wont be for a little while. i will keep you posted though on my progress. just got the 3-3.5 lowering kit for it, for starters. got some escalade 17" to start with but i plan on gettin the
22's soon. ill give ya the link to check out what im lookin at.

From now on, i will call her project "ultimate". lol. for now she wont be that ultimate though. lol. ill keep ya posted. and get some pics as soon as i get the 17's and the lowering kit on her.

thanks,
proud owner of project "ultimate" lol

[DefEddie]

Definatly check out that link I sent you,depending on when you get the 22's I might take those esky's off your hand's.
I've already got the front lowering component's on my 2dr,just waiting on time and the temp outside to cool down so I can do the rear.
If your pumped about doing the torsion key's yourself I would rethink it unless you have a lift or someone experienced in 4x4 torsion bar's.
The tool is almost essential,though you can get by fine with a 2 jaw puller if you don't mind living dangerously(don't do it)
I've yet to even adjust mine down since I took them out.
FYI,after you pull the stock key's you can sell them on here to someone with a NBS that want's to lift it.

[97'hoe350]

the link to the 22's im thinkin about gettin is http://www.centerlinewheels.com/whee...id=1&sw_id=358 i picked up the lades' for $200 with tires they only had like 100 miles on em. it was a steal. but i got some stock hoe wheels on some (very very used) stock f-250 tires (they are like 2 inches smaller than the stock hoe' tires.) the backs tires are just barely legal and the fronts have the metal showing. so the tires are shot but the wheels are like new. no curbing no nothing. so if ya know anyone who will need em in like say... a couple months. not gonna put the lades on until i get the front end allined (it is all out of whack)

When you compare the hp/tq numbers from the 572 to other crate engines, it's not that impressive. The intake runners are only 310cc's, that's not nearly enough for that size engine. You'll be dealing with header and other tall deck issues that get expensive quick. A well built 540 will make more hp/tq, built on a short-deck platform. Shoot, a well built 496 will make more hp/tq than you'll ever have need for and blow the tires off at the blip of the throttle and can be built for half of what GM wants for the 572. Forget a warranty - if you ever race it, even a street stoplight race, the warranty is void.
Plan to invest a ton in tranny, rearend and suspension as well. Big-inch engines tear crap up and are great for finding your weak links.
I've never seen one of the big-inch engines that would pass emissions, they'd need at least a 1050 Dominator or a high $$$ fuel injection system to supply enough fuel and keep from burning pistons due to lean conditions. Drive behind somebody with a Dominator sometime - after a few miles, your eyes will burn and you'll see what I mean.
Don't hang your hat on being the only or first to do it. There are a lot of folks out there with scad of cash that build some insane stuff!

[97'hoe350]

ya know of anyone who has put a 572 in any late model trucks? i'd like to know what state they are from. washington has pretty average standards for emitions, figured i would try to get ahold of a guy who is an emitions tester. think my dad knows one. i'll ask him if he thinks it could pass. as far as y i am doing this, it is because it is different! some things that are different might not be the best things out there, but thats ok. take rat rods for example. they are just expressions of people's personality. some of them might not be the fastest things out there or the "nicest" out there but the owners love them as much as a guy that spent 2 mill on a hot rod or something. thats what cars are, an extention of their owners. and thats what min will be too. so what if it wont be the most powerfull thing out there it will be kick ass. no offence intended.

thanks for your in-put,
