In 30 years many cars have been sliced, diced, taped together and repeated several times.

If you wanna know for sure pull a valve cover, slap on a new $3 gasket, and shine a good flashlight down to see what you're dealing with. Lack of extra hardware in there when you open it up would be a good indicator too.

Even if it's a non original motor, numbers running to an early 305 that should be FT, I've seen people waste stupid money because "it's what I had so I'm building it"... so converting even an early model ragged out old base 305 to roller isn't unheard of either, dumb as it is resource-wise.
