"Old" and "new" are relative. You're playing the Snob Game. It's "Well, I'VE heard of AND know all about them, let's move on...." type of thinking.
Even if it's been out for a year or two, it still might be the newest out there. And still worth discussing.
Don't play dat, Homie....

That block in the link is the same as mine.
I would certainly recommend it if Mr Kupon needs/decides to purchase a new block.
He will also need to decide if the weight penalty of iron is acceptable or not and go from there.
In terms of camshaft specs, something like a 250/264 114 LSA +4 or for something milder a 245/259 114 LSA +3
If you go cam motion solid, add 6 degrees of duration to each side.
Current specs will also work too, but for a 440 I would say they are adequate.
It will be interesting to see what direction this build ends up going.

This is the reason I hate this Damn site, there's always someone with some BS remarks saying some BS. I just said old news which it was or is, and if it's something new I'd like to know.

Just chill.
Nobody hates you.
BTW, if you hate this site why are you back here?
It seems to me something always pulls you back in like a magnet.

Typed this and was about to walk out the door 🤔 let me do a quick search... We'll get some results soon enough.
https://www.dragzine.com/tech-storie...1-ls7-top-end/
The block and it's thread, but i don't think it's the same as the 440 link which doesn't share the same name of project number cruncher's. The 440 build is on Dragzine, Engine Labs also. They all share threads Lsxmag,Engine labs, Dragzine etc....

There are so many builds out there, many on this site, who can be copied as the results are already known. It comes down to picking the power level you want and how you want to make it along with how much you will need to spend if your current parts are not usable.

Let me correct that a bit. Quality parts without drastically different standards in consistency will yield similar results. Shitty castings, be intakes, heads...etc will produce different results.

Yeah you only have CID and rpm and your compression and fuel limits and that's going to mostly set how much power you make. With this long runner intake limiting RPM to under 7K I would make it 500 inches but that's not possible but as big as you can. Then fix the FUBAR valvetrain that this other shop put on that engine and you should be good. I guess the 87mm TB isn't hurting you but you should take a look at your MAP over 5000 RPM as well as it doesn't look like there's a crossover but maybe there is? With an NA piston and ring stack you can do 4.250 stroke in your sleep with that block and more. The other people giving you advice on this haven't really done many of these larger engines at all which is obvious.

That still doesn't mean you weren't pulling vacuum as each cylinder can only see an 87mm where as on say an MSD intake each cylinder can see the 102 as only one cylinder breathes at a time. If there was a crossover then it would be more like a common plenum with two 87mm TBs nut it looks like they are separate plenums.
Do you know what your MAP was at WOT from 5 to 7K?

I never got to make any real pulls on it. No way of knowing. Motor was DOA. Its OLD news. With the Holley dominator, i ll have no problem figuring that out in due time. Unfortunately, we didnt get that far. The plenums are completely seperated. We are using the Holley and speed density. Looking forward to some real fun like analyzing kpa data, etc. It just didnt work out. Nor are we gunna keep this combo. I can promise you, if I ever get the oppurtunity to dyno, i will be bringn 2 extra 90mm or 102mm tb s with me for quick n easy swap testing. Bcuz its that easy n quick. Unfortunately, none of that is likely anytime soon...: /
