I don't think I would want to be the test mule and do R&D for your deal down tsk 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 work
