I'm curious tho @ wut hp levels will things start failing? With me running cams and springs/retainers and NBS delete on top of the mp90 running 30ish lbs. When should I consider upgrading pistons rods or gettin a Girdled block?
Our stock rods have been proven to fail just north of 500whp by ZZPerformance
Our sleeves, pistons/rings are prone to cracking/breaking @ any PSI really. The greater the PSI, the less margin for error.
You can run a stock sleeve, piston/ring setup @ 30 psi safely... If it doesn't knock, IAT2 is where it needs to be, and EGTs are in check... it's unlikely you'll break something; unless one of those three occurs causing the other two to follow.

FYI... with cams and ported head... you won't be near 30 psi on a MP90.
Y do u say that? I'm debating if I wanna put cams in now or wait for Girdled block. I will b doin forged pistons rods valves and such. I will also b porting head when I do the build. Don't think I will b before tho. Unless Jr wants to hook a brotha up. Lol
im not gonna list off my mods again, but i am doing everything but the sleeves on this motor. I have a sleeved big bore block already that i will be working on when the car is finished. I was around 362whp when i lost number four, but my meth didnt kick on at the track. I had 82k worth of hard racing miles on my setup that was completely stock. had the meth kicked on id still be running the stock motor. I have since will be going up in compression and have some goodies already in my motor 
Well see how the stock sleeves will hold as i will be pushing them to their limits with the new setup

time to ditch the Heaton! 
lol thats not a bad way to do things! if i had the money i'd have a built short block myself. how do u like that zzp cams? and how is it with the upgrade compression on the pistons? i was thinking of going that route
