Warranty Block?

That was 45 yrs ago

Still worthy of a "D-oh!"

The best I can tell it was cast on 2/8/72. There is no tag riveted to the block. All 16 lifters are oversize. Mopar used to sell oversize lifters. When I bought 16 for this engine about 85 or 86 there were only 52 in inventory. Unobtainable now.

Do any of the cam companies offer them?
