My car sounds just like yours, except mine had the duel snorkel air filter, but my car had the "N97" Noise reduction package, and that got duel snorkel air cleaner housing.
I think California cars got the "N97"
I guy just showed me how to find that out on the build sheet, it is not on fender tag.
So that my help clear up air cleaner housing differences between the engines, one was built with the standard air cleaner and cars with the "N97" got duel snorkel.

I also think mine has the "301" intake manifold. But the rest is the same. I have not had the oil pan off yet to tell if it has a windage try, I would guess that it does not have that.
