That's why I say this all generally comes down to personal preferences and compromises, that combo obviously is a combo that fits you, that's why I try to give info for the OP to pick what's best them cause how the hell do I know what there gonna like or not, a lot of people assume their likes and dislikes are universal, I doubt anyone here would of recommend any of that for you if you were new to this and asked what to build. It might be a build the only fits you or might be pretty universal we'll never know most would be talked out of building anything like that. To me anyone interested in a 273 build should look at your car and toolmanmike's.
