Block ID
I am looking at a car with a 3999290 casting big block with a CE stamp. The owner claims that it is an original 4 bolt main. I looked it up and it comes up as a 2 bolt block application. Any chance that it would could have been a 4 bolt? Would 4 bolts produced in the early seventies for replacement have use used the same casting? Or more likely I am just being told a story?
