World Products LSX Block And Heads!!!!

[chuntington101]

Found this the other day and thought it might intrest some of you looking into the LS7, or boosting a LSx engine!

http://forums.corvetteforum.com/showthread.php?t=1202653&page=1&pp=20

the block features 6 head bolts per cylinder (but dont have to use all) and the engine can be taken to (a possiable, still waiting on World for exact details) 454 cubic inch!!!

also there are heads avaliable that are like a LS7 (inlet) and C5R (exhaust) hybrid! and having 6 bolts should reduce the chance of head lift when youing boost!

so looks like a "better" (read possibaly cheaper) alternative to the LS7! oh and they are going to be doing them with SBC mounting points (just for you guys) as well as ls1!!!

454 lsX anyone??? :)

thanks Chris.

interesting ???

all we need now is an LSx cyilinder head that has exhust ports that masch thoes that are used on the SBC, that way the standard ultima exhaust could be used. Mabe American speed could look at building a ultima specific engine with the world industries block

still dont know how you would get this pased some of the emisions regulations though, i would think that it would be likely classed as a modified engine.

would make for an easy install of a fule injected engine though, just grab that block, sutiable heads and exhaust, a modified LSx wiring harnes and standard LSx computer module, custom efi fule pump and surge tank set up and get all the drivability, cold start and part throtle control of the late modle engine.

i think thats the main advantage of running the LSx series engines, plus the added benifit of it being all ally from the start!

i dont think it will be too long before engine builder in the states start using them (or offering to) for their crate engines. and thanks to the potencial for larger CI these things should make some BIG power and remain reliable!

as for the emisones thing, well you could always use the exhaust boxes that Gman uses! they have space for cats in the back right? maybe turn them around and run the cats first? also i think header would be wuite easy to get hold of! if you look at the forum in the above link you will find loads of turbo kits that mount turbos forward. so just ask them to fab some headers for you and the swing them around!

i think it would be a good idea for American speed to start to look into the LSx stuff! they may as well get on the band wagon before its full!

thanks Chris.

Thing is, this will be competeing with C5 stuff, ls7 stuff, lsx stuff and Darton products and what may go against it is the fact that it has 5 bolts around the cylinders. You will have to buy the whole package and be tied in with them.

With the other options most of the parts can be interchanged with stock or aftermarket lsx stuff.

Heads shouldn't lift off the deck. That would tell me there was either some detonation or the cylinder pressures were to high.

It will be interesting to see what the price is.

[chuntington101]

there is pricing on there boosted. i will endvure to find the post. the same post also states that standard parts can be used inconjuction with the block, and that includes the heads! i assume it will be similar to the World Windsor range as they aslo have extra studs ( knows why they can make more than enough power) but i think stock heads can be used with them!

on the head lifting thing. i think it was more bown to to high presures as apposed to dept. i know about a year gothere where loads of stories aobut guys lifting heads on relativly low boost applications, but i haven't heard of any recently!

thanks Chris.

[chuntington101]

ok found the info! you may have to use their heads as well, but it appears as though all the components are interchangerble! so if you already have a cool top end you could just swap them over! anyway here the detials, inc prices!

I hope this answers more questions. All prices are retail. I have not heard the max bore. 4.250" is the max bore on the iron block, not the aluminum. Given the cylinder wall thickness, I'm not sure you'd want to go to much past 4.125"... still, this still gives 454 ci capicaty.

this was a direct quote and im only passing on info! to see this post go to www.ls1tech.com/forums/showthread.php?t=390595&page=4&pp=20 about half way down the page!

Thanks Chris,

Some of that stuff looks quite interesting. I'll have to get a look at it when it's marketed.

here is a little update from a recent show in the states! sounds even better than before!!!!

500 cubic inch anyone?!?!?!?!? hehehehe

thanks Chris.

[Boosted Ls1]

That's one heavy looking block! Looks like they just made everywhere thicker then GM who kept it light and put in ribs where required. It's probably stronger but the extra weight looks substantial. I bet there are some internal features which will be critisized (sic)later on. There's a market for it though.

[chuntington101]

i agree boosted! it looks like they have used 50% more metal than GM did! but they are not going to be doing an iron block so they need to make this one strong!!!! i think it will still be alot lighter than the iron LSx engine that GM offer (100lbs more than the GM ally blocks) and if it can take the boost/power that they offer, it should be a very atractive alternative, if a little more exspencive!

but just think of a 500 cubic inch LSx engine in the back of an ultima?!?!?!?!?

thanks Chris.

[chuntington101]

just found the first place thats going to be selling the World Block!

thanks Chris.
