the clock on the block looks like to me it was cast 6pm second shift ,the pad on the front of the block should be about 4 1/2". is there any #'s on that pad ? it has to be a 4 bolt to be a 69 block,there also may be a # on the tranny flange.looks like the heads are on the block and from what i see maybe correct for the block,send me those #'s & i'll look them up to see.
