Well - we finally found the issue with the engine. We popped one head to check and found a blown head gasket. So took off the other head to inspect and found a cracked head. Had lots of fun trying to find a 302 head. Finally found one that would match and rebuildt them both. Installed new push rods while we were at it, new plusg, wires, coil, rbuilt the carb and installed electronic ignition. Walls look good and rings seemed fine. Went for a spin and wow nice to have 8 cylinders firing now!! Seems to have lots of power now. So we are back on the trails
