as for a 454 vs a 6.0 a ly6 makes alot more power in stock form and torque numbers is 30lbs less. ly6 with a cam gains 75 hp 75 tq just from a cam swap and still can been street mannered like its bone stock. thats a vortec one from 99. i dont see a carb one making that without a serious cam headwork intake and so forth. by the time you spend that kind of money you can stroke a ly6 to a 408 and cam it. 408 would not be touched by a 454 unless it was a full build talking aluminum heads cam intake all that. parts for a ls are cheap. we aint even talking about the fuel to feed this. ly6 isnt great on mpg but not terrible and get really no worse with a cam and tune but a 454 built like that is going to a be a very thirsty girl.
