Well the I guess near original engine in my 1934 PU is loosing its bottom end. I bought it in 1974. Someone I ran into is going to destroy an original restored 1980's era the same and is trying to pre-sell me that engine. All I can get out of the ill-informed is there is an angle drain **** on the front and on the right front p***enger vertical side of the block is the relief cast "Diamond" and next to that the single letter "R". Is this a post-production "diamond block" ? ? I have a Model A post production Diamond block but don't know squat about V8's. Any help ?
I’ve never heard of a diamond block V8 either. But it could’ve happened. Since the theory is that they were produced after the cars were older, maybe it has loose bearings too?
