I picked up a Holley 300-36 dual plane, the Z/28 clone, and I am curious as to how old it might be. I know Holley has shuffled names around for these intakes over the years and that the 300-36 has had at least three but does anyone know what time periods they covered? Mine is a "Street Dominator" and I believe this was followed by the name "Street Dominator II" and "Contender". There was also a 300-1 single plane "Street Dominator" and I think the 300-38 dual plane was also called the "Contender" at one time. I found a number cast on the bottom just below the part no. and catalog number, it is "070998", could this be a casting date? It's not really important, I'm just curious.

I bought the same intake for my son's truck that you have described, Street Dominator, and I really like it. I will be buying the same intake for my daughter's truck as well. I am not sure about the casting date on it though. Anyways, you will not be disappointed with it.

This is just a wild guess but, i would say if it has the bore in the front for the oil filler neck it would be late 70's or older.... If it is cast with a boss at that location but no hole late 70's to mid 80's... no boss at all later then the mid 80's.....

I remember seeing a few of those in the late 70's. The dual plane intake is a great street intake. Too many folks do not realize they have smoother torque curves.
