I bought a crate 302 here recently. I was looking up specs on it (just out of curiosity, and there are two different 302's made in '69 (the year the company told me the block was). On is the 302 "F" 2V 1968-1973 and the other is the 302 "G" 4V 1969-71# Boss. While I'm sure that it will be the first one, I just want to know for sure. Is there a way I can tell by looking at the outside of the engine? I don't really know enough about internals to go tearing it apart (hence the reason I bought a crate engine instead of rebuilding one).

Just 'cause it's so pretty, I'll post pics.

 

The 302 Boss uses Cleveland style heads.

 

Boss was '69 & '70. That engine in the pics is a standard 302.

What did your specs say about cam, rods, rod bolts, compression ratio, valve size, valve springs & max rpm, valve seals?

 

That's one thing they were supposed to send me but didn't. I need to ask them about it tomorrow when I talk to them. The only "spec" sheet they sent me was a receipt saying I bought the engine.
