I am starting to build the engine for my restoration, and have two options to consider. I do not have the original block or internals (I think), but according to the VIN the car is a Q code.
OPTION 1:
It's was my dad's car and he had a performance shop build the engine for him when he was 18. He said it was built for high compression but doesn't remember the HP it made. They used the stock 4V heads, added an Edlebrock Scorpion intake, 1050 CFM carb, electric fuel pump. This engine is not in running condition (Even though it has less than 20K miles on it), having zero compression in the #6 cylinder that we believe to be a hole in the piston. Too advanced of timing possibly? We aren't sure what was done internally to the motor (He doesn't remember), but I don't think it's the original block because it is stamped as a DOAE shown in the pic below. I am doing my best to scour the web for stamp code information, but it seems that the information is not always consistent. I am not finding anything that matches this--most sources claim that the code should be DOAE-L,C,J, etc. Does anyone know what it means for this block to not have that secondary letter?
OPTION 2:
Mileage - unkown. My dad's dad (My grandpa), found a 351C-2v motor at a junk yard and bought it for my dad as a gift, in hopes that he would drop it in the Mustang to get it running again. This engine is supposedly in running condition, but has had no internal work done to it. It is a D2AE-CA block, which I believe to be closer to a "number matching" block.
I'm looking for some input on the two stamping codes, more specifically is one a better block to start with than the other? I am leaning toward the hi-po engine that my dad had built as a kid (OPTION 1) under the assumption that the internals were beefed up so there would be less work I'd need to do. I am looking for something in the 300-350 HP range, nothing crazy. Numbers matching is not essential, but of course would be a bonus. Thanks in advance.
