that makes a bit more since, im guessing the max bore for the aluminum will be 4.15, maybe 4.16
a 390 borere would work great for a turbo or a 417 (3.9 stroke)

 

Hey All,

I posted a reply in a similar thread in the Internal area which i have cut and pasted here. They had also brought up cylinder heads and passing this info along also.

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 what all will be inner changeble? anything?

 

Absolutely bad ***! This makes my block decision a no brainer. Boost junkies are going to love this!

 

I definitely agree that this is bad *** but I would like to know what is innerchangeable and why they didn't go with an ls1 style bottom end such as 6 main caps?

 

wish the heads started out bigger then 68cc's or 62cc's for the 12*
with a 4.125 bore the CR will be high.

 

I was thinking the same thing last night before I went to bed.

 

Use dished pistons.

 

theyd have to be dished quite a bit can they dish them to 28cc's that would give a 8.3:1 CR on a stock stroke and stock gasket thickness
youd need 36cc dish to get it to 8.3:1 with a 3.9" stroke
a 39cc dish to get it to 8.3:1 with a 4" stroke

i think you need to take some out of the head.

 

Just to keep the thread interesting, I thought I'd spice things up with some pics that Vtespeed (thanks!) took from SMEA...

 

awsome! the heads will come 72cc chambers!

the heads say they have C5R intake runners any info if it would take the stadard ls1-6 style intakes?

any clearer pictures on the info sheets, my eyes hurt from trying to read those.

i didnt see the biggest bore the block will take, i think i made out it will take up to a 4.2" stroke, then calculated that with a 4.125 bore. 45X cubes.

 

block/heads dont look done to me....if they dont have a casting with holes drilled and threaded for SEMA i dont think its commin out in the next month or two...could be wrong though


but man does it look nice thus far.

 

uhh this is kinda a dum question im new to builing whole engines but that block is bear corect no piston and no crank ect...

 

thats correct, you get the block then put the assembly pieces in


reading the heads more i think it says it has an LS7 intake partern, can an ls6 style bolt up to that? id hope to run the carb intake.

 

for those of you who can't read the info...

its LS7 intake and valvetrain stuff. Maybe an SB2 will work. I heard somewhere the SB2.2 single plane intake ports line up with C5R stuff.

 

now the block stuff

edit: saw other info above.
Just noted this for those ofyou trying to read the spec sheets in pics.

 

ah thanks!

im curious to what intakes will be availible

 

I will proly go and by another fbody or ybody to stuff that motor into. that is going to be a nice piece. cant wait for it
