1969 Zl1 Intake Casting Number Question

[69z28rsbilly]

Did the early 1969 Zl1 Camaro Intakes have casting numbers ?
As I have seen a lot of early "198"Factory Winters dated 1968 BBC open divider intakes with no casting number or the last three digits factory ground down and hand stamped 198, and some with a raised boss for the casting number but left blank.....
I was thinking of buying one without no casting mark but dated late 1968....
Thanks in advance....

The only builds that fit the "early" category would be #1 & #2 final-assembled December 30, 1968. Both had pilot engines built at Flint late November. It is possible they had hand-stamped intake manifolds.

Thanks William

 Did the first two 69 ZL1 pilot engines have the casting number( or a number) cast in to the block(between the two ribs) above the timing chain cover ?

thanks

Only the block from #1 still exists. It is no different than the other known production ZL1 engines.
