Leon contact Scott Brown, he has some good info on these engines. Over 426 will require a custom crank and getting rid of the factory reluctor wheel off the crank. No big deal as you will prob just run a external crank trigger anyway. No one has really built one of these engines for nitrous, But imagine this, 426 cubes, sheetmetal intake, fuel injection, 2 foggers could be 4 stages of dry nitrous.....I know sounds pretty nice Oh yea they have been making in the 800 - 850 range already NA with these engines.....best part is they are considered Small Blocks by most racing sanctions , at least for now...LOL
I think the biggest problem ,when you get to this level , will be head gasket sealing.
Mopar should have the extra bolts on the head and block.
You would have to machine it but have them there.
Leon, Kurt Busch is in super gas and running an aluminum G3 with 1600 hp and thats with 6.1 heads.
Apparently the 6.1 don't flow well above 8000 rpm  but the 6.4 heads take care of that.
He is at 8:30 at 168 with 17 psi turbo.
The guy who build the engine is Donnie Lewis at MERE.
Now for another question which block to use?
Are all the block the same except for the level of machining?
And remember that with a production head
