I think it's a 352 bb fe engine but I'm not sure any help to identify it would be great

 

I have a 63.5 galxie 500 fastback. I thought it had the 352 in it. It turns out it was the 390 . I do know they did put 352 into cars in 63. Google your part number off the block it will come up the info you need .

 

Where would I find the part number on the block

 

They every where stamped on the head.side of the block
Even on the intake. It will start out with letters then numbers.

 

The only way to tell the difference in any FE engine is to measure the stroke, casting numbers will show all pre mid 70s FEs as a 352
