What engine do I have

I recently purchase a 65 Thunderbird. I know the engine is not original. The 65 came with a 390. The block was black and the valve covers were gold. Mine is blue. Is there any way I can find out what I have?

sorry buddy i dont think you will get much help here most people chating here modern cars w/fuel injection.
i know ford had different blocks back then if it has fat heads its probably a clevlend.
for more help try one of the other links on this website like classic cars,muscle cars,or ford general

The 65 only came with a 390 engine. It's probably a rebuilt one that was just painted blue. Take a valve cover off and see if it has a rocker arm shaft that holds all of the rockers. If it does then it belongs to the 390 family of engines. It may even have 390 embossed in the head like a small block which you can see when you take the valve cover off. The "Clevlend" 351, which I think Innes is referring to, was used in 1970
