Title: 3927184 Intake
Post by: Red955i on March 15, 2019, 12:15:31 AM

Were these manifolds cast in both Flint and Tonawanda and if so were there any markings to denote this? I have seen a few with 68 dates codes have a large T near the casting # which would (to me) indicate a Tonawanda manifold. Others have no markings. All seem to have a large R on them near firing order?

I've also interpreted that 'T' to indicate Tonawanda, but I can't prove that...    :)

It would be interesting to here if someone with an original Tonawanda built car had a "T" on their intake, or if they didn't

FYI..the non-T intake I believe is the original incarnation. It starts off with the oil filler tube hole then blocks it. The "T" intake, which I believe (but cannot prove is Tonawanda) does not have the oil filler circle.  Does anyone have an original 69 with Tonawanda engine that can confirm if their manifold has a T?
