Hey, I had my starter off the other to replace (Not that replacing it actually did anything, but it was worth a shot I figure, it was old) and I took down the block Numbers. I know that the engine in my 66 coupe isnt original, but It would be nice to know more specificly what engine was in it. (Specially since the previous owner was rather vague)
The Numbers/Letters were:
6A21
0C5AE-6015E (0 is zero, looks like it can be either O or zero, but its zero)

Can someone tell me what that means? Or better yet, point me in the direction of a web site with that kind of information, so that I can archive it for later use?

Thanks Alot
