i'm in the market for a new 235 block for my truck. i have found a few but they are not in running condition or removed from the vehicle so i cant verify the condition of the water jacket. i plan on rebuilding the engine so the condition of the bearings and such is not that important to me. the conditon of the block itself is.

i know to look for a "lip" on the top of the cylider. i have also been told that the water jacket often cracks on the driver's side so i could look there for an obvious crack.

are there any other key items/areas to check?

thanks
