Someone is trying to sell me an L72 427 engine with block casting number 3916321. I need your expertise to tell me if this could be a true L72. If it is a correct number, I will look further into the other markings on the engine. What other block castings were used in 67-68 L72 engines?
Thanks for the help!! |
