easy there guys was just asking a question based off what i read on the GM sights.. and granted that is true that they have to thow out conservative numbers to protect themselves, that is why i was asking... glad to hear that it will handle a lot more than 500. but like i said if you go to GMpartsdirect.com they only rate the block at 500HP.

was looking at putting a steel crank and eagle or crower rods in a stroker with the LQ9 block, L92 heads and L76 intake.
