Best Carter 4 Barrel Carburetor for a stock 273?

Hey it's hot, real hot. I had a guy working for me who looked like it was,raining where ever he walked.
He said it was worse than Nevada where it was hot but was a dry heat.
He used To live in Manhattan Beach .ca. you would think he would be used to heat? Was a retired surfer dude with a few loose screws.
lolz. i'm socal native but have lived and worked in a wide array of locales and the whole "dry heat" is a very real thing. humidity kills me, because i'm a delicate flower.

full disclosure: i worked in NO and beaumount for a spell. no thanks. gimme 108 and 10% any day of the week.

oh and manhattan beach is very temperate. most of the beach cities out here average temps are in the mid 70's year round.
