Ladysman on H-T lasted a couple years and still running fine when he upgraded to forged internals at 250+whp on a stock block Z6. Norcalcrx on H-T had a stock block Y8 that made 250whp and 251wtq at 10 psi for two years until he cracked a ring. Both of these members boosted hard and drove these cars daily.

BoostedED9 who made the 302whp at 16.5psi blew up his Z6 because he turned the boost up over 20 psi still with the stock block.
