I have more I'll check when I have time. We're getting ready for B.G. That one was on top of a stack of them.
Checked & nothing too close. Have a M17 which may be too early although I looked at my 10E bodied S1 & was suprised it had a J9 intake. https://www.v8buick.com/index.php?threads/70-cast-iron-intakes-3-of-em.393881/
Hello all, Thank you for checking. I think in may found a good candidate. Not perfect but close. Still looking for something closer to A28 date.
