340 & sounds the part too. Very surprising performance on the road considering the economy gearing. The body is in excellent shape although the car has 128,000 miles. The original AM/FM radio with rear speaker works great. The vinyl seats (with bucket backs & fold down center) look like new. "Roscoe" is quite the cruiser, comfortable, especially in the summer with the original AC pumping. Have to have AC in a black car with black vinyl top & black vinyl interior!
