is this true about a 350 sbc vs a sbm

i wasnt arguing with the guy, i kept to myself cause of my job, but ive never built engines, and i just wanted to know. but iagree with you guys, every body and their dead grandma has a chevy, and i have the only power wagon in the area let alone the onl REAL macho edition in the area. i just figured id ask cause im sure some of you guys wether you want to admit it or not have played around with other engines and such. i actually like fords, and exotics to apoint. but i dont like chebbies at all.
