Looking to buy/build 500-600 fwhp 360

use to be a big long thread bout 8 pages trying to find any body that has had a catastrophic engine failure with a LA small bock where the block failed but cant find it! there plenty of blowed up 5 an 600 hp engines, but none could be blamed on the block!! lest outta 8ish pages of post! most agreed that 600ish was the limit for a stock block....DWB
