Thanks for the advice. Unfortunately, I don't know why it was partially torn down. My grandfather bought the car about 40 years ago and I think he never worked on it. It's just been sitting there.
One post above mentioned pistons, valves, and timing gears are available. How about connecting rods, push rods, valve springs, rocker arms, cam shafts, hardware, etc.? Is it only the block, crank shaft, head, and manifolds I need to worry about?
Thanks.
