Hello, All Team Camaro People
New to Camaro world OLD to the Corvette side :thumbsup:

I am going up to the Boarder this weekend to look at a 69 Rs/SS 350 car for my Son that is suppose to be in a person garage for the past 23 years. The fellow I am speaking with claims the car is 12c 3rd week in Dec 1968 and the motor casting is 3932388 and dated L178,December 17th 1968.The stamp on the front pad is T1217HA. Now is it possible for the motor casted 2 days before it was build and Installed2 days before the 2nd week ended. I do look at and old calendar and the month of Dec 68 Falls perfect in line
Dec 1968

What are the chances of this being correct I will have him take some Pic's of the car when we go up there Sunday. Also I have read the 69 ss car should have the z28 386 casting is this also correct. Sorry if I am asking stupid question but in my Corvette world there are more Fake cars then real cars.
Thank you all for your help

Yes it is possible for the block to be cast and assembled this close. In fact it is possible for the cast date and assembly date to be the same day if the block was cast early in the day and the assembly was done on a late shift. The cast number is most likely a 386 since it is often difficult to make out the difference in a 6 or 8 digit. Oh and by the way all Camaros are perfectly legit and we have never seen any fake ones built.....must just be a Corvette thing

His block could easily be a 3932388 block, they were used in that time frame too.
An SS would not have a Z engine in it at all either. A Z is a Z with the 302 engine with proper engine numbers to back it up too. A Z block could also be either of the ...386 or ...388.
Keep in mind, the ...386 and ...388 blocks were nearly identical. Its what's inside the block and on top of it that make the engine what it finally ends up being.

The 388 block has the casting date located next to the casting number, behind the left side cylinder head.

There's no such thing as a "302 block" (Z28) - 302's used the same 350 block as millions of other Chevy cars and trucks; just had different crank, rods, and pistons installed in it to make it 302 cid.

That is also discussed here:
