i have four pontiac engines in my garage, there is a WT,YJ,YY and a 1970 YS block out of a 1971 gto. i took the engine codes and did a little research. anyway, my question is what are they worth???

 

I would guess they are worth what ever you can get for them

 

What you have block codes, WT-66-389-67-71-400-73-455 74-76-4OO. these are the engines with that code. Your YS-65-66-389,67-76-400-78-400. The best code you have is the YY. And as posted above thay are worth what you can get, Are all these engines compleat? If you post the head numbers i can give you more info. A good 400 or 455 goes for around $300 with out the heads, Block and crank.
