Evening all
I would like some help identifying the stamping from my 1970 442. I believe I know what it reads but want other opinions. My car is not numbers matching. This is just more for my own knowledge. Rather than influence your opinion I will wait until a few have weighed in as well before posting what I think it reads.

 

30M120436 is what I see.

Concur. The 30M1xxxxx means that this block did come out of a 1970 A-body car.

 

I read it as 30 G 1xxxxx. Framingham. Glad I asked. Thanks all.

 

? "G" or "M"

 

Judicious application of a wire brush might answer that question, but I see an "M".

 

Agreed.

 

After some elbow grease
M it is
