well i never got around to saying the previous owner wash what i call rich lol anyways i ran the head numbers and there a 70s-80s 305 head i think they put those on for more compression and start of summer i notice new frost plugs in it so i took off intake and heads to find it being really clean and new lifters/cam/ .040 pistons pulled oil pan and one main cap to find new crank bearings and looked to be machined crank the cylinder walls still have the machine crosses in it. seeing that the motor has been rebuilt and not run much at all but i got to find out what type of pistons are in it? what cam is in it? and what has been done to the crank/rods
