Can't believe so many are against going 4bbl, who the hell wants a performance engine with a two bbl, it's basically free on tap power, it's two bbl 99% of the time and 4bbl when needed no real down side if chosen and setup right.
Like people said performer or similar intake, even stock 340/360 and a 600 ish carb, I wouldn't use the stock 273 intake doesn't look like much of a performance piece to me.
Nobody's saying they're against a 4 bbl., just that it isn't the priority until he gets his other ducks in a row. And yes, a 2 bbl. can perform, just look at Sportsman short trackers all across the country.
Ignition first. Then exhaust. It's no benefit to get more air in if you can't get it out.
