Best intake manifold and carburetor for a 273

I believe anybody can figure out I'm sarcastic talkin about a Super Victor and .750 roller for a 273. That said, my serious recommendation would be a stock Commando 4 barrel intake and a nice modern Edelbrock 500 AVS. That's be hard to beat, IMO.

....and @3forty, I'm glad to see I am still living in your mind. That makes me feel so special, you'll just never know. lol
