    I don’t know my carb bases. The two barrels from ‘55 on all look the same to me. I was going to put a newer ‘70 Rochester on this.

    The intakes look different, you'll find a choke stove on the 66 intake, but not the 56. The large carb bases were not used on all the 2bbl engines, you'll find a small base on a 307, large on a 350, iirc.

    Thanks Squirrel, I think the 2 bbl is from a 307.
