Installing a 4bbl on a 273 advice

Remember, the optional V8 for 56 Corvettes was a dual quad 265. Had 225 hp vs the 4-barrel version's 210. They were small four barrels, though.

Here's a dual quad 273 on the cover of Hop Up Magazine, June 1965:

What a crude set-up for this 273, 65'. Dual quads, with stock exhaust manifolds!!! Remembering the NASCAR set up. Single 4 bbl on the 426 Hemi's in their NASCAR's and duel carbs on the production cars. I heard it was a way to slow the Hemi down. Of course, extra add-ons would make a difference. It's all in the complete package.
