Even if you could prove, drop dead certain, that your block was a '68 or '69 302 Z28 origin, I don't see anyone really being that interested in a 50+ year old bare block, no matter it's history. There's just too much stuff going on today with the newer engines.

not raining on my parade. it wasn't my idea that it was a 302. others suggested it on this sight and others. Yes I agree many hotrod builders are using the LS engines today and they are in the limelight because its the latest and greatest. However, there are many more restorers and clone builders out there in this industry! If this was a rare engine I would rather sit on it till I could find the owner of the original vehicle. It is however, date specific as casted and can only have been installed in a 1968 or 1969 Chevrolet vehicle originally,which would not necessarily be a Camaro of any kind much less a Z/28 . Don't mind sitting on it a while longer if theres a chance it may go back under the hood it came out of! I have no use for it myself anyway except as trade/cash value to put towards locating and purchasing a set of 1971 Ford 429SCJ heads to go with the 71 429SCJ block, crank, and rods I'm also sitting on and will be using!

These are the numbers I get from Mortec

3970010 69 302 Z-28 2 bolt mains
3970010 69 327 2 bolt mains
3970010 69-80 350 2 or 4 bolt mains
I have a 3970010 block in my 76 Corvette
