That kind of stuff is my concern.. will the motor have to come out to remove a head? If I do go in the 440+ ci range, the single plane intake will be the ONLY way to go, hence why i was concerned about the intake clearance.. I already know that a bunch of milling on the intake and elbow will be needed in order to make that work, just wondering how much more. I also wonder if a motor plate mounting setup would help.. could lower the motor an inch or something with that style setup... or maybe even modify the aftermarket K member that I will be running by then and make it sit the motor down an extra inch or so.

I believe the cast in liners have ribs around them to keep them in place and I've never heard of any issues with them... only the pressed in liners. How big is the flange on your sleeves vs. the C5R sleeves? Are the steps in the block (the material the sleeves sits on) going to be prestressed or conditioned to remove or minimize the initial material deflection which is common with "new blocks"? From what I understand it is very common for the steps to compress in new alloy blocks after heavy initial use. I'm not suggesting this is going to happen with your blocks, but I'm wondering if there's anything else you guys do to prevent the sleeves from dropping other than just using the larger sleeve flange.

The reason I bring this up is because the big bore Darton sleeves that are commonly used here are notorious for dropping sleeves (in new blocks) if the blocks are not conditioned, and these sleeves also have a larger flange. It's not much of a concern if the blocks have already been stressed, but when they are pressed in a new unconditioned block the chances of the sleeves dropping slightly is pretty high. It is now standard practice to condition the steps before pressing in these liners to prevent the high failure rate that was seen early with new blocks.

JL,
I don't have an F body so I can't help you, but yes... I would think it would be a valid concern. I suspect a motor plate would allow a better fit with a taller deck, but I don't know enough about the F body configuration.

FWIW, I believe WP is also working on an intake to fit their tall deck block. I don't think it will be ready when their blocks hit the street, but they are working on something. I can't tell you anything about the height or if it's a single or dual plain intake... maybe they will let the cat out of the bag.

I'm not too worried about it yet.. I'm looking a couple years down the road at this point. I have a th400 setup I'm still collecting parts for... after that goes in I will have alot of suspension tuning, and weight reduction to do, as well as getting used to leaving off a transbrake with the power I'm already making with my h/c setup... so there's alot to be done before another motor goes in the car. I'm just intrested to see what and if these issues are bringing up, and what the findings are.

If it turns out to be too much of a hassle.. then I may just have my block resleeved and stroked.. I think that I should be able to get into the 430 CI range with that, and most likly I will keep it n/a.. no more then a little 100 shot just for special occasions.... so that being the case, I should be fine with it. I'm only looking to go mid to low 10's on motor with no power adder and running pump gas.... I think that if I can get the car into the 3500 or less range with me in it, that shouldn't be too hard to do. I figure 530 rwhp thru my th400/4500 converter/12 bolt should be enough to get me where I want to be.

In the end.. a mid 10 sec n/a car is what I want. Nothing I have to pull the motor on every year, valvesprings, yeah that's fine. Tranny refreshening, rear end rebuild, fluids, brakes, shocks, all that stuff is fine... I just don't want to be doing a motor rebuild every year.

My thoughts are to go as big on the CI as possible.. the more displacement it has, the less radical the setup will have to be to get to the goals I have in mind, and the less major overhauling I'll have to do to it on a regualr basis.

Definately work on that carb style manafold... should I take teh world route, I'll most likly do the block, heads and intake... as it will most likly be the best work together setup.

As for the header sizing.. i figured a 2 inch primary, we are looking at big block displacement, why wouldn't we need big block tube diameters!

As for how that will fit under the hood.... that is a good question. I really wonder if it even will, or if the whole thing will have to be assembled then installed in the car, most likly thru the bottom. Never mind plug changes! These are the things that are going to end up being the deciding factor as to what route I take. I kno wthat 1 7/8 step to 2 inch will fit, and if nothing more will.. then I may end up going with my stock block and some aftermarket head that will fit it. All I'm after is enough n/a power to run 10.30 give or take in a 3500 lb car... so I'm not looking to beat down the world (no pun intended)

Chris,
That idea is under consideration at this time , but as the program is just beginning, our focus is getting the big chunks on the market.
We aim to supply the 2 types of blocks, 2 types of heads and hopefully the Dominator carburetor manifold by springtime, the latest.
We'll post word as the program progresses.
Of course, popularity in the market will tell us a lot.
Thanks,
MerlinPro

I'm with Chris. I'm interested in a long block as well as a shortblock... How much will this stuff sell for? How much for just the block/heads/etc.

Thanks!

Andrew

thanks andrew. be really nice to see these engines go up again the ls7. i think it could be the creat motor to have!!!!! i think it could make a real impact in the kit car/replica/hot rod market!

Merlin Pro, i understand, you got to walk before you can run!

Andrew,
No decision on short / long block offerings yet but market acceptance of the product line will help determine, so I can't give you pricing.
However, short and tall deck blocks range from $3999 to $4199 ( including ARP hardware on the billet main caps and about 35% less than C5R block) and the 12 deg. and 15 deg. heads range from $799 bare to $1134.99 assembled. A Warhawk -specific ARP head stud kit is mandatory for our blocks but hasn't been priced yet.
You can call our sales dept ( 631-981-1918) and request a four page flyer depicting the parts and cut-aways (as illustrated by Warhawk 1) which describes all the tech features. You'll see why it's gonna be bomb proof.
Sniff,
Cast and machined in good 'ole USA. Source this offshore and you'll instantly have 20 competitors on the market with your exact design. No thanks.
Chris,
Hope your thoughts come true.
Yes, even 800 lb. gorillas (also hope) have to take baby steps!
Thank you all for your questions and interest. Warhawk 1 and I will respond as time permits.
Regards,

What is the max stroke on the World block? Is the limitation deck height, pan width, cam interference, etc.?

Also, it has thick walls and liner. What is the biggest andticipated bore? Could it be re-lined as a 4.2?

David,
The block right now in as cast state can spin a 4.25" stoke with no modification. One of our crank manufacturers is supposed to be providing me with a 4.5" crank. I believe (without actually looking into the matter fully) the counterweight swing is not the real problem, it is the con rod bolts that causes the problem. I have to see if we have the stock to macine a notch for these bolts but also the stock to move the outside oil transfer line out board to leave a safe amount of material. Also I don't have the cam to crank spacing on instant recall either so I would need to investigate that.
4.200"? Well the block could be bored to that no problem, If it were mine would I do that? No. A PART of what I believe makes us better than the competition is sleeve thickness. High horspower users (1400-1700hp) have ballooned cylinders and cracked GM Blocks. Boring it out to 4.200" would make our sleeve .0075" thinner than the other peoples block sleeves (C5R). That would bring us back to a weaker condition. I realize bigger is almost always better but in this case discretion may be the better part of valor...

how big would it be at the standard bore with a 4.5 stroke, thats a freaking big *** motor

i wonder how much power could be made, in a streetable setup, id bet you could push 700rwhp easy and drive it around all day long

69,
As MerlinPro stated before 4.125" bore x 4.5" stroke = appx 481 ci

Quick Reply: 500 ci LS2?
