Sounds good. Basically the block will hold what I throw at it? (within reason) Like 800-900 rwhp should be no problem with internals? Also whats the weakist part in our motors? Rods, pistons or the crank or something else

The real trick is to keep the heads from lifting off.

I thought the sleeves were the weak point, now the heads too?

Sleeves are not a weak point on stock blocks, but on resleeved that is another matter. (Depends who dun it)
I would never trust but 1 company, R-E-D

Ok so will this be ok? 900RWHP on the block with a nitrous application No other variables Just will the block hold it? 900RWHP on nitrous Unmodified block only honed out for freshened up with the new internals
How much nitrous are you thinking of throwing at it? Keep the stock crank and block, forge the pistons and rods. Get heads with a thicker deck and tap for half inch head studs. I think youll have a hard time breaking that.
stock are M11, which are impossible to find except the custom ARP studs. A machine shop can drill and tap for a larger bolt or stud. I wouldnt trust doing it yourslef with an angle drill with the motor still in the car though!
