Hi boys, I have a 360 engine with heads, the block is stamped 3418496 7. 360, and date coded 8.12. 71. heads are 3418915 f, and 3418915 g. part no on piston skirt is 3418919. im wanting to know some spec on these parts, am I right in thinking these are high performance closed chamber heads,same as the 340. also what would the comp ratio be, im assuming with the part no that the pistons are stock. lastly I cant think what this engine would have been fitted to from the factory, I thought the highest performance small block from that year would be a 340. any help greatly appreciated. Richard. ps cast crank part no 3418640.
