Take some pics of the motor...there was a difference in the valve cover and a couple different things from the 400 to the 426. The 450 is really really different when put side by side with the 400/426 motor...

The 450 has the oil fill cap on the left side of the case. The 400/426 are filled through the frame. Also, the 450 does not have a manual decompression release like the 400/426.
