I don't know but I just finished a 2001 block that makes 1060 hp and I have zero concerns.

I am looking to go Supercharger. I'm not getting any younger so before I can't race anymore, I figure I'll spend the kids inheritence. Looming for 2400 hp. So you do need to ask!

How do you tell the date? Just picked up a Hemi block and haven’t seen a date I don't know - I bought mine new in 2001 so I know it was 2001 vintage.

Pre-World are usually very difficult to tell the manufacturing date.
Even with the later World style, all we ever got was a machining date....Dalton wasn't required to stamp the blocks or anything like that, so the casting date is a Mopar Mystery.

Supercharged and 2400hp?
You should be looking for a better block IMO.

How do you tell the date? Just picked up a Hemi block and haven’t seen a date I don't know for sure but my mega hemi block has 11 94 on top pad and 6K29 on side. So it could be Nov. 94 or might be a 1-19-2004 or neither. lol

Can't answer the question, but as I understand it the survival of a block depends in part on how the power is made. Supposedly nitrous is the worst, followed by normally aspirated (high static CR, high RPM), then boosted. I've heard (but not agree at this point) that twin screw (Whipple, Autorotor) is the roughest of the boost group, turbo the softest, but no actual results. 2400 sounds dangerous, but then I'm old.
At that power level I can't see aluminum as safe weight saving is erased by worries about water leaks, ring seal, inconsistent oil pressure, distortion. Those serious-but-budget LSX engines use factory iron blocks. My 183" Toyota L6 iron block is supposed to be safe at 1,500. Why is nitrous "the worst"?

Those top fuel aluminum blocks handle 10,000 hp are they any good? Look at all the big HP hemis running pro mod and every other class...all aluminum blocks. The chevy LS guys are using aluminum blocks more and more too. One of the fastest stock block LS cars in the country is an aluminum 5.3 based build. I helped a friend with one he took to Lights Out at SGMP.

These are uncharted waters for me. Not sure what a good mopar performance mega block can handle. [/quote] I don't think I would want to be the test mule and do R&D for your deal 2400 HP sounds like it is directly in the danger zone for standard cast grey iron I have a new Koleno high nickel block that I want to use to build a N/A Top Sportsman motor that will make north of 1000 HP with a set of B1-MC and dual dominators on a tunnel ram, I'm thinking it is good to 1800+HP. I have a new KB aluminum wedge block on order , Tim at FHO tells me it is good to 4000+HP

See if you can get in contact with some top alcohol engine builders. They will know what will work and more importantly for how long.
