ive voted tall also, due to the fact,we have a ls7 block as stated,and there is guys wanting to swing 4.25+" cranks and long rods,and make larger cubes.
i know this is not for everyone but choices are good,raise the cam is always good, just adds the building time/money for a custom large cube engine,
just my 2 cents.
cheers dave

Adding 2 more to the LS3 block would be better only because we'd have a 4.060 bore to start with that one.
Adding a bunch more material to the bottom 1/2 of the block so that it doesn't move around like the lsx block does, changing the water jackets to just a small round hole rather then the oval ones that contour the cylinders to prevent it from cracking like a few lsx blocks have would do a TON for block rigidity as well. Raising the cam up a 1/2 inch would also be a vast improvment, priority oiling for the mains also important, having a provision for oil squirters at the back of the pistons, would also be really nice, like the LS9 block has.
Basicially, that adds up to a new block. I really wish that Donovan would get on board with developing a block... they probably could come up with a really nice piece that would get the job done, and could come in price wise at about where the world block is, but they have the chance to do the 6 bolt setup the right way like GM did, rather then having a stud inside the intake port like world did, which IMO is

Most of the problems that we have seen have been from inexperience when building a high horsepower small blocks.
Read some of the posts on that tread. You have Joe from Six Speeds Inc as well as Erik K adding his opinions.
As far as the cracking I need to see pictures if you have them. I am not calling BS but I need proof. I agree in my opinion I would like to see a closed deck on any block that use in a high horsepower application. To justify these type of changes I need DATA. Not rumor or hearsay. Give me DATA. Pictures and all the details.
I'll post a link to that thread in a few minutes so I don't lose this post
