Here is something you don't see everyday.The block casting number is G 10 8, July 10,1968. The engine pad is stamped T0709 July 9,1968. any idea how this could happen?

If all is genuine, I'd suspect the boys just didn't change the gang stamp for block stamping and the earlier stamp date ends up on the later casting block. . How much time usually goes by from casting to assembly? . What I'm wondering now is, isn't this Vin shown 18N468959 in the range of a June build car? ~ Pete

This car was put in storage in 1977 with 50,000 miles on it.I bought it 1n 1984 with the 1977 lic plates still on it. It now has 68,000 original miles and I have all the service records.and pop.I too would like to know how long after casting do they stamp it.

can you tell from the picture if the broach marks look ok? Does the vin #468959 fit with a 07C build?

This is not unusual per Jeff Dotterer of Dated Components. The Deuce engines generally have an 3-5 day span betw/ the casting date and the assy date, far too close I thought, but apparently not (?)

I would say it is rather unusual to have an engine pad stamped prior to the engine being cast. I have never seen this with a factory stamping prior. It would have to be a factory mistake,IMO.

definitely unusual, I have had this car fo 20 years.my father bought it in 1984 for $3,000.I'm sure it's the original engine.Does the pad look ok?

Are you sure that isn't G 1 8 with a screw head after the 1?

That is as dead on for a factory stamp as I have seen Broach marks look good. I don't know the idiosynchrosies(sp?) of the plants vin derivaties,but the Tonowanda stamp
looks good also. JMHO...Rich

I forgot to add that I have seen motors assembled the day after casting on Mid Year BB Vettes.

You should check a Julian calander for that year. It just might be that it was cast on a friday and then assembled on monday when they forgot to change the stamp...you all know how Monday mornings can be.

Rich,

Nah. That's no good. July 10th, 1968 was a Wednesday. But I agree with the "forgot to change the gang" suggestions.
