351c Block Casting numbers!
This must be the most confusing thing ever! Where they all on drugs in the factory when they built these things?
I read and read and find so many conflicting arguments regarding the casting numbers on these Cleveland blocks that I am clearly uncertain who to put faith in!
Seems like a simple request, just need info but you dive into it and nothing makes any sense at all!
I will make it short, I have a "M" code 71 convertible XR7, been parked for 19 years and has 60K I have service records but honestly cant be sure if they are complete but no reason to doubt them. Had small items done at the dealer when new ect but nothing serious as with the rest of its mobile life. I will be restoring the car, engine is stock and have pulled it to see what it needs but the cast number on the block is D0AE- there is no letter following it and the production date is Dec. 5th 1970. it has the 4* closed chamber heads and does have 4 bolt mains. I read on many sites that this casting number was also used as Boss block, but find it hard to believe a 71 cougar would end up with a BOSS block! So what do I have?
