is either intake correct?
For my 71 454? one is GMT 3866287 H18 70 and the other is GMT2 338789 C 8 73 (as best I can tell with the paint build up) The intakes look the same except one has a block off plate bolted to it next to the t-stat. TIA

It's interesting to see a '74 MY part cast in March '73. Car production didn't start until August so that stretches the 6 month rule in NCRS. I wonder if this manifold came off a late '73? I've already demonstrated that late '73 SBs got the '74 part number manifold, wonder if this is the same thing.

I would want to keep the numbers matching intake on my car....there is no advantage using a 73/74 intake.....Price? ck ebay or google corvette intake.
