770 or 804?

[Dhunter1231]

Thinking about a big bore.  I don't want a ALL drag bike, I want a all around bad ass machine that dunes and drags!

My mods are HC3, JE 11:1, KW springs, Port Polish, FCI, +3 TB, and I'm thinking about using Team Rocket Factor.

Which one is better? How reliable are these builds? Should I even do it? Is there something better?

RaptorRandy has what I'd consider a pretty reliable build. He's rockin a 780.
