Re: Chevy Six Cylinder Casting Numbers
Greetings
My 1971 C10 (SPID indicates a base engine 250 ci) block has a date code of A 71 (perhaps Jan 7, 1971). The block # is 3994257 which doesn't show up on any of the listed resources. Any idea how I can authenticate this motor #? Oh, it's a Fremont build.
thanks
