I don't know the exact detailes, but some ( most? ) B and E bodys had iron intakes. Every G body that I've ever seen had the aluminum one though. I guess they figured the weight savings wasn't worth it in the bigger cars since they were already tanks!

50 bucks . It has the typical corrosion around the water ports but i reoplaced the gasket and i had no issues i can build up the coreners where it is corroded and re shape if for no cost but you migth have to wait a few months before it is available. maybe sooner but right now i got my 77 cutlass and my fiances k5 blazer both in the garage . if i get the rear end done maybe mid febuary.

I owned 3 early 307's, all were iron intakes. I bought a used A4 from the USA, not looking for a needle in a haystack. We never had 307's in the 80's Cutlass up here, except the Hust/Olds, 442 and 88 model year. Only aluminum intakes I have seen up here, were on a 84 Hurst/Olds and later swirl port motors. That included a 87 chebby caprice, factory Olds 307 powered.

I meant factory installs
that's a 1972 casting, pre-EGR
The chance of it being factory installed on a 1984 is zero.

======================
I take it that is the ubiquitous #16 casting then, or perhaps #17- large ID typically in the depression aft of the front water crossover... Will have an EGR valve.

I have seen an aluminum a4 before, but in my opinion they are far less common.
I forget the casting number for the irons, because I usually just scrap them.... but I believe it's the same intake as the 403 motors.
Just like a #16. I just recently gave one to Milan so he could flow it. Try PMing him for the details.
