This is a 347 stroker motor but I'm not sure what the block is. When I bought it, it was said to be a Ford Racing engine with a Boss 302 block, but it doesn't have the screw in freeze plugs and I'm not sure if Ford Racing put the screw in plugs in there blocks. So, without taking the motor out and taking off the oil pan, I'm trying to figure out what I can from this garbled code, it looks like it starts with "Y", but what do you think??

 

hello;

it looks like the date casting starts with E which is an 80's block.

it is positively not a boss anything. you were given very wrong info.

 

What do you think the 4 means?

 

no clue but it doesn't matter because it is not a special block. it may or may not be a roller block.

 

Oic, we'll at least I know...
