My doomed 408 build

Wow. Sounds like he knows there was screwed something up with number eight that he didn’t like the looks of. Have the lifter bores been revised? Did it wipe out the cam lobe on #8 exhaust first? If it did, you know your fitment in that bore is bad. Unfortunately, it’s not really a secret that Chryco had some of the worst lifter bore machining tolerances and stack up tolerances during manufacturing. What year of block is it? UMWA negotiations in the late seventies really didn’t help matters out. I had a coworker that had an uncle that worked on the truck assembly line in Detroit then, he had all kinds of tales of sabotage when things got ugly during contract renewals.
