Had a formerly reputably machine shop line bore a block and install four bolt mains.He made the thrust .023" too narrow.Had the block brazed up @ the best shop in town. Block split #4 web and was losing HP on the Dyno.Was making 588HP@5800 & 603 #s @ 4300.Then it was all downhill power wise.was losing a little oil pressure and each sucessive run was down 20 or so.pulled valve covers and saw metalflake. I would never braze or weld on a structural cast iron part again.
