My doomed 408 build

Oh yeah and a side note that was a 403 Oldsmobile 6. 6 and the year before when we were having it built he had to Bush one of the lifter holes as when they put the in there it dropped in with major Slack! And also that wasn't the problem when we brought it in. Turned out that after we retighten everything down after break in a custom rocker was hitting the cheap valve covers that my customer put on. We doubled the gasket and Presto. it kind of sounded like a knock and we were not going to go any further till in was diagnosed. Doubling up the valve cover gaskets LOL off we went. I know it sounds simple but something like that? Ted has been doing these motors for over 50 years it was obvious. ONCE HE COULD SEE IT AND HEAR IT WITH HIS OWN EYES AND EARS.
