Maybe. This engine at local yard, has what I believe to be a '70 intake, and a '71 block. PM if interested. Don't know all the date codes on these, versus Chev so any input on where to look is appreciated. Guessing "C" is March (1970). Hardware (intake to head) would be included.
C= March. Code is just in front of carb base. Has letter and corresponding numbers for day. I found this link on the site for addl info http://www.v8buick.com/index.php?posts/1036000/
I have a "B 1231718 E";date code: C 13, if nothing else above works out for you. I'm in sunny South Florida. Will ship! Thanks, Bob.
Here's an intake for my 70 stage one built the second week of March 1970 this is the original intake C-4 march 4, 1970 a week before the car was built. Cast parts were very close to the build date of the car sheet metal, carbs, distributors a different story
Any date would be good up to a week before the car was built. I haven't checked my heads or block for Date codes yet they are the Original block and heads .
