273 solid lifter motor

This car is owned by a a MOPAR guy I met a local show. I know some of the other MOPAR regulars there and they vouched for the car as an original solid lifter motor with domed pistons and 10.5 compression. It has a recent rebuild with additional mods that should have it close to 300hp. I'll know more this weekend and post a pic if it's OK withthe current owner. I think trapster is right it's going to boil down to how it feels after driving a built 340 for a while. Might be a real fun 2nd car though.
