I would be interested to see if anyone can help me out in finding a 1967 327 block #3903352 or 3892657 cast in September or the first half of October 1966 for a 10D cowl tag with an original engine plant date code and "MK" engine code for a 275 hp. with manual transmission, still on the pad. I also would like to find a pair of cylinder heads #3890462, to put on it. The original heads were obviously built with 1.94 inch intake valves but I also would consider a pair with 2.02 valves as I am considering filling the block with L79 parts for a little fun. If anyone can help me out or has suggestions, I would be very grateful.

Thank you
