Edelbrock S.P.-2P. 318 2V Does it even exist??

Why would anyone want a 2 barrel version? A 4 barrel will get better mileage every time with careful driving.

The guy has 3 different year model years NOS Carter 2 barrels to choose from. I believe mid 60s, a 69 automatic and an early 70s.
To me, a good choice would be a 4 bbl. intake, like you mentioned, with one of those aluminum Holley model 4360, 450 cfm carbs. Anyone have an idea what list number is correct for a small block MoPar? A Holley catalog in the late 70s would have the answer.
