no reason why it wouldn’t work here and it’s a great block for NA power. And always go to the larger bore for NA power. And they have longer cylinders to control a piston with a 4” stroke. That’s what it’s designed for
I’d only use an ls3 block if I had it. The cylinders can be wonky in them

Thing is, it you're going to use a LS7 block, just build a 427. It's less work

Check the cost of a Ls7 block used or new vs other LS blocks for resleeving... Get a good resleeve and you can drill the block near the cam for bay to bay breathing from the front to rear. Steve @ RED trick. Whole thing is the cylinders moving with higher hp levels....
Get a good decent prices block resleeve it move on. Any ? Call Steve @ RED or have your Rep contact his buddy Zach at TAF.

I am building a similar motor to what you are building(big power LS3 topend) except I have a lot more constraints. What I have researched regarding blocks is this. For NA max power and best bang per buck, Dart Iron, the end.
Now if you want alum, that's a different boat. Per Steve at RED, LS2 is best to resleeve for NA. As Smokey said, he can do a 5.3 and bore holes in the bays, but nobody that I know of has tested their effectiveness vs og bay to bay venting. I would never do an LS7 block unless you bought one already resleeved. Cylinder are thin as factory. If you fubar something, they only have a .005-.010 overbore, that's it-then you resleeve. The Dart alum is the winner for a lot of reasons. Yes, they cost $$$, but you get so many upgrades, it's totally worth it. By the time, you resleeve an LS2 or 5.3 block, ARP the mains, and prep, it's about $1200 or so difference to go a Dart. JMO, good luck!

Had a good talk with my sales rep at FED, going to hold off a lil until my customer makes a decision on what block. The way we spec'd the heads caught their attention and CF would like to over shadow the build. So this could be a sick build lol

After my post on Darth's Math thread.....something hit me. Y buy pistons twice. I've paid for assembly and waiting to get the top end back. So I called JE piston, told them what I had and no longer intended to use the pistons. 13'ish, just Ain't enough and using corn. 10% restock fee 90 bucks and get the ones I had been looking @ for the other set of heads. With 62cc's and a flat top I was @ 13.1 depending on gaskets. Now looking @ 13.1 with 68cc's. Talked to the rep (Frank) i talked to before when I asked about Carrillo Dome tops. There for a ls3 but has a solid dome for fly cutting when swapped to my spare Ls7 heads. Now looking at about 14.2 on compression. Not being scared to talk is a win.

. quick search and ...facts. I've talked to Steve more than I care to say. Big bore Hunter...You name it I've asked...Plasma spray liners (Ref. 5.4 with no sleeves) as well as any idea that has popped up on sleeves and bore size. 4.200+ °
