Re: 69 DZ 302 Engine ID.........
DZ is nothing but a suffix code. At least the block started life as a 302 it looks like. All those 4 bolt blocks could be in many applications. Have to see if the crank says 1178 on it. Its casted on the first throw up by the balancer. That is a Z/28 crankshaft. Rest of the stuff looks pretty good from here. DZ code looks like January 7th of 69.
