Thanks for the kind words. When I bought the car it had a 454 and a different TH400 in it, the born with motor and trans came with the car and have recently been freshened up(new rings,bearings,cam). The block is still standard bore. The transmission was cleaned and inspected and both motor and trans were put back in. The new motor has about thirty miles on it and the over all mileage on the car is about 68k. It does not have front shoulder harness seatbelts.
