Don't know about the other stuff, but I'm skeptical of a 12 sec eta in the 1/4. I mean look at warmonger's time and he's pushing much more than 320. My guess is mid 13's, maybe a low 13 with good traction.
I like your thinking though. If and when I get to seriously modding my SVT it'll be a 3l and a 100 shot of N2O from a Venom system..
