3914660 casting on back of block= 68 327 large journal crank. Date code H157. Did chevy make blocks this early? August of 67. The block was decked, the only stampings on the front pad I could find was TO and H.

Why not? They would have needed them for the 1968 model year start (typically in September).

One of the first. :cool: Thanks Rich,

I have a camaro 327 MA coded stick motor dated K 10 7 - PAT , .040 OVER stock 4 bbl q-jet , saw your signature and thought you and I are neighbors with the same kind of cars , few west coast members out here ! DON.T NEED A DRAG CAR 1966 DO YA ? HAVE ONE IN SPOKANE , been waiting on a old 85 yr man to let me have his 427 tall deck to go with the drag car , he won't buge ? ITS IN WANTED 66 SECTION, if I get the blk I'm starting it , your signature made think of the dragcar

The next car I pick on to play with will be a DROPTOP 66 chevelle or a 67 RS camaro.
