I just bought a 61 Chevy apache 20 with a 235. well it ran but found that it was putting water in the oil. So i pulled the engine took the head off and found that number one piston wrist pin had worked it self out of its original position and made a nice deep groove in the cylinder wall, all other cylinders are good and the head is cracked between the valves. So what am asking is the 235 a good engine and if so im in nebraska and cant find parts or another engine. Need help.
