The question is, did Pontiac ship 10,000 (or more) SR blocks each year? Or were SR numbers picked at random. I just don't know at this point. But I'll keep looking!

Mike would like to know: Did the 455 ci or SD use a 60-80 psi pump spring that was problematic 1n the early 1970's that a mechanic helped the factory in testing and development due to a spring pressure issue, causing those Engines to fail early? " Not" the fuel being the actual cause of failure on those 455 ci Blocks.
