Based on my 1980 Vette Vin Number, the engine is an L-48 but the air cleaner is a dual snorkel with the front center air duct. All parts suppliers like Corvette Central and Eckler's show a single snorkel air cleaner for the L-48. The engine looks to be original.

Was there a change in air cleaner system at some point or was it an option of some sort?

Not sure what year, but at one point, ALL the later engines used the dual snorkel air cleaner...I think that started around '78-'79...

My '80 was built in November 1979 and it had the dual snorkel air cleaner.

My '79 L-48 was built in July of '79 and it came original with the dual snorkel air cleaner.

Thanks for all the help.

Corvette Black Book says they started that on the '79's to gain about 5 more hp on the L48.
Nice looking Vette you got there. Like the color.

Yep, ALL '79s (til 82 ) had the dual snorkel air cleaner AND the 2.5" exhaust.
