I have 3 core 455 sitting around.....I'd like to keep 1 but it doesn't matter to me which one. All 3 turn over and have been stored inside 1st is a 70....its without the valve covers....but I have some stk covers if needed 2nd is a 72 3rd is 76...has carb and her dizzy 70 has best factory compression, 76 is said to be strongest block, 72 is what I would say is most likely to be the nicest of the 3. Ask 500 each. I figured 250 for block, 150 for crank rods and pistons, and 100 for timing cover......all other parts are just a bonus to the buyer Prefer pickup but shipping at buyers expense could be arranged. engines are just outside of mansfield ohio
