aluminum or cast intakes

hey i was looking over ther rules for our local track and it says that you must have a factory cast iron intake manifold well i have a factory aluminum intake so i called the TECH guy out at our local track and he said that you must have a cast iron intake well i have not been able to find a cast iron intake i have tried many many junk yards and i cant find one do any of you guys know if the 84 OLDS 305 came with a cast intake or where i can get one or if they didnt come with one where i can get proof so i can show the TECH guy that so i dont get disqualified for running it cause we are responsible for what we run thanks alot

Are you sure they don't mean Heads?

no they mean intakes the only race cars that run aluminum heads are latemodels and we dont run those at our track the rules state you must have factory cast iron intake and cast iron exhaust manifolds

So if the engine came factory with aluminum it's illegal? 84 Olds was a Olds 307, is this what you have?

yes if it came factory with aluminum intake its illegal unless we can prove that they didnt come with a cast iron intake and they only came with aluminum thats why im on here and stuff yes its a 84 olds 307 thanks alot

That engine in that year was aluminum only, at the time I was an Olds SM.

When did they start using aluminum intakes? I thought it was a real long time ago.

ok now is there another way to prove this for example going to the dealer and seeing if i can get one or what also are there other intakes that will work that are CAST from different year cars cause im sure they will ask me that at the TECH
