Stock LT1 crank hp level?
355 LT1 block- all new bearings,freeze plugs
I'm up grading to a T-trim and want to push max 10-12psi and have a FMIC. planning on making 500rwhp and wanted to know if i could use my stock crank,stock main caps with ARP studs? LS1 cranks seem to hold up way past that. i'm running forged blower pistons and forged rods.

also two years ago i bought valve springs from combination motor sports and i'm not sure what they are exactly. all i know is that they are ex-612 springs. does that mean anything to anyone? they renamed to NRP and i don't see them on there website. i want to know if these springs are strong enough for my blower setup. are my stock 94 harden pushrods good enough or should i up grade them as well?

thanks just tell them i want to know if they will be okay with my motor pushing 10-12lbs of boost with a small cam. LT4 hotcam or comp cam thats around the same. i know they are good for 600 lift.

Yeah, the rpms help a lot, but I said I wouldn't trust it not that it wouldn't handle it. And you could very easily go to 851hp and have it let loose, or have one bad detonation and lose it. Just doesn't leave any margin for error, IMO.
And I just know mine would let loose at the worst time, like at the 140mph mark. I would feel like I was sitting behind a grenade.
GM even went to a nodular iron crank for the LT4 and their HP rating was much more than the LT1.
