[Chevelle-List] What is it from

[Didmon]

Gentlemen        I have an old G.M. aluminum intake manifold on the original 283 in my 64 Chevelle,and I was wondering if someone can check the numbers for me so I can find out what it was from. It reads 458520 G.M.,and then under that is 61AH30D.Is it early 70's Camaro?                                       Thanks,                                       Grant
