Chevy's new Big Block "572ci" !!!

I was watching "Trucks" on Spike TV Saturday (the Copperhead Project) & they put in Chevy's not released yet, Big Block 572 that is supposed to put out over 650HP & close to 800' lb tq. This motor is supposed to be a daily driver on nothing more than pump gas. With this all being said, the wheels are turning in my head (< that's a bit scary) & I'm thinking about putting an end on my S/C project on my 03" S-10, and am leaning towards buying a mid 90s model S-10 for the body/frame and dumping one of those big block 572s into it. I think I could produce a nice 10sec Pro-Street Truck. What's your guys thoughts and opinions on this little pre-stage project? I know you guys might think it's a little crazy that I would put so much stomp in an s-series truck, but it's just my cup of tea. I appriciate any and all feed back on this!




Thanks
Jay

Didn't see the episode of trucks, but all the info I have on the 572 tells it to be 620 HP for the street and a full race 720 hp version And not even close to street legal.

expensive crate motor.Would be the envy of all the street guys I imagine. just to say it .......572 aaaaaaaaaahhhhhh.
would be curious to see the shoe horn needed to get that sucker into an S10 don't think the HEI distributor will fit up against the firewall. Just guessing but I think some serious reinforcing and rewelding of firewall and frame may in the plan.

620hp would be plenty enough for me! There would absolutely have to be some serious fabrication as far as the firewall is concerned. I would like to think I could do this whole project for right at $25,000.00. You want to hear something scary??? "I've built drag quads that cost more than that!" Makes me kind of sick!

The 572 dimensionally is different than stock big blocks(taller and wider). Now taller can be dealt rather easily but wider in an s-series is going to create alot of problems and you are going to spend some cash on custom fab headers

I'm going to call them up this week and get some dimensions on the motor & dicuss the application in an s-series truck and see what the true tale of the tape is. I will be sure to report back with all my findings. I have quite a bit of research to do at this point. And if I can do this project at $25,000, it will be a go. I will be able to save a few bucks on metal fabrication as a high school friend of mine works at the local race shop. And like you said, Heigth wont be the issue as much as width. I also have a 9" ford rearend with 4-11s sitting in my garage.

I don't think theres anything wrong with a 502 crate motor. I just don't mind spending the little extra coin for a factory built 572 that puts out some serious HPs right out of the box.

Saw one of these in the flesh this past weekend at the Houston Autorama. The GM performance team had a huge display setup with all their latest goodies, including the new 572, sure looked sweet.

You only live once. If he has the bucks then why not. Besides 502's are common. Go for it.

Well I'll be calling GM Performance tomorrow to find out what the release date will be on this motor along with the ins & outs of stuffing this motor into an S-Series truck. I'm sure you can obtain this kind of power from building other various motors at a cheaper price tag, I just like the idea of buying a motor built by GM themselves that puts out that kind of HP right out of the box. I still have a lot of research to do on this little project & I'm looking to have all my ducks in a row before I start. I will have lots of reports as things progress & will be looking for lots of advice along the way.

I know you guys probably think I'm a little off tilt for wanting to stuff a motor like this into an S-10, but I tend to like things a little bit on the unique side.

It has a mis-matched cam(low torque, high HP) and aluminum heads I dont like. I think it's nice to have 572 cubes, but the price is way to high. This engine will have alot of high end/high speed power, but suffer in the bottom/low end.

Does'nt really sound good for trucks.

The lowend torque of the motor alone will overcome any short comings the camshaft may have down low... This thing will scream at both ends so, if you have the coin... More "power" to you.

Well yeah, but only cause it's got so many cubes to it. The things is way too cammed though, could be a serious torque monster with a lower duration cam.
