Very Early 1966 427 blocks

Patrick: Will make some comments under your comments above.

Larry- Since that block was a late VIN car, you must be right. Tonawanda must have cast both 942 blocks and 351 blocks in early June 66. The beginning and ends of model years seem to produce interesting anomalies.

Note: see comment #16, a correction that the early 351 block cited was cast F 17 6 not F 1 6.

Patrick: Would also like to hear your theory on how late in the 66 year was the 942 cast? Also was there a time
frame where GM/Chevrolet cast both 942's and 351's. Thanks>Larry

Larry- I shouldn't have relied on my memory when I said 942 blocks ended in May since I had a F 1 6 351 block at one time. I went back and checked my records, and my early 351 block was F 17 6 not F 1 6. I still think GM did not cast a block and its replacement at the same time. However, your F 6 6 942 block is no longer an anomaly in regard to a F 17 6 351 block. I can only conclude that the last 942 block was cast some time before June 17, 1966
