There was some misinformation in my original post (sorry). Here are the correct specs:

- 9.24" and 9.8" deck heights. (9.24 is stock)
- Will swing a 4.250" crank
- 6 bolts per cylinder (yes six!), extra bolts are at 12 and 6 o'clock.
- The WP block or heads can be used with non world heads or blocks.
- The WP block has a priority main oiling system (GM's does not). That is why they have to run such high oil pressures... The thing that needs the oil the most, gets it last (crankshaft).
- The heads will be LS-1 or LS-7/C5-R Combo (LS-7 intake C5-R Exhaust).

I'll pass any further info as I get it.



This is going to be the cat's azz!

So let me get this right... I can use the WP block with my existing AFR heads???

Hey All,

Some of the preliminary info was in this thread a while back.

https://ls1tech.com/forums/generation-iii-internal-engine/330018-4-125-world-products-bare-block.html

Most of the info here is pretty accurate. There will be a block at SEMA, but it will not have water jackets in it as of yet. The block coming to PRI should have the water jackets in it. The head availability will be nice also and along the same timeline. Get your wish list in line for Christmas.

On a side note, we have also gotten a couple 225cc Dart heads in for testing and show a lot of promise. As this info comes around I will pass it along.

Have a great day.

I have heard rumor of the block and head combo dwarfing the current C5/6R block and head combination. Oh yeah, did I forget to mention that it will be cheaper than the C5/6R items.......??? Not to mention that there is someone out there in the head business (can not drop that name yet) that has already gotten 320+cfm out the head already.... and there are two intake cc sizes to choose from.

Looks like the LSx market competition just got a big shot in the arm.

Hey All,

A little more info for you. There is a possibility of a World Products block at SEMA with coolant jackets in them. Proposed ship date of the first prduction blocks will be 2/06 and quite a few orders are placed at this time. A World Products head will be there also, but a solid non-jacketed version for show. Chamber sizes are proposed at 58cc and 68cc options.

The Dart heads will be available in 205cc and 225cc runners as cast. Prelim 225cc tests show in the 310-315ish CFM as cast.

There will also be two other companies (not Edelbrock or All-Pro) releasing castings and assemblies not only in 205cc & 225CC versions, but also 240cc and 265cc in the LS1/6 style heads and also LS7/C5R styles. Intakes are also being developed as a complet package.

Bear in mind that with all of the aggressive packages there will be some differences. Though they will be bolt on in relation to cylinder head to block and intake to cylinder head, there will be some definite changes in the valve train area to keep geometry proper. At this time there are some folks using .200" long valves and related parts. But with some of these heads, .500" and .600" long valves will be required as well as different pushrod lengths from the norm. Some have higher valve cover sealing areas to clear most roller rockers and some are even offset. I mention this as often folks think a bolt-on is always simple and in this case there is a lot to consider in one of these aggressive head swaps. Nothing outrageous, just different then usual.

It will be an interesting trade show season to say the least. Hope this info helps. Thanks.

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.

I'll let you know if I hear anything else.

So why didn't they make the bottom end similar to the ls1 and give it six main caps, or maybe they did I haven't looked at the .pdf yet that I got of this same topic in the force induction section.

4.250 BORE for the Iron Block?How much does thIron Blocks cost? $2,000 for the heads? Thats a good price! When will these parts be available?

Miles in Florida

What's the minimum bore size with these heads? 4.060" like LS7 heads, or will they work on a 4.000" bore LS2, or even a 3.898" LS1/LS6? If you make a 12 degree head that works on a smaller bore, I bet a lot of people would buy it for their existing LS1/LS6/LS2 motors. Probably need a smaller intake valve to fit, though...
