The part number is #14057053 if you look under that number you will see GM CFM 20. On the Lg4 it will say GM CFM 16 but will use the same part number.
But anyway $31.67 shipped
I have 3 305 4bbl engines I pulled out of cars 2 of them are Ho motors one form a 84 camaro 5 speed car and one form an auto they both say cfm 20. The third is out of a 85 camaro sport coupe it has the same part number but says cfm 16. I called a friend of mine that has a mint low mileage unmolested 84 berlineta and his has the same part number and says cfm 16. If your looking for an original 84 intake form a ho car I have it. Other them that I know nothing if somebody can tell me what the deferens is I’d like to know myself?
"All US-delivered carb'd V8 3rd gens had an aluminum intake manifold - and they were the same part whether LG4 or L69 (except the '87 LG4, which had the center two mount bolts on each side at a different angle than the rest - '86-earlier were all the same angle)."
My old LG4 was equipped with the alum manifold.

These are all 82-86 Aluminum intakes with the same part number. The intake with raised "ribs' on ports 2-3-5-8 is about 1 pound heavier than the other 2. ( I removed ALL the fittings before wieghig each. )
