340 w/ 650 double pumper ?

I've got a tuned 750 DP on my built 360... bags power everywhere, starts easy, only gets about 7 mpg! Great to drive but you couldn't use it every day (but we try :) )

My 340 has a Holley 670 Street Avenger. Awesome carb. I tried tuning it on the dyno and couldn't find a thing wrong. Go up one main size, I'd lose 5hp. Go down one main size, same thing, lost 5 hp. Super carb right outta the box. I wouldn't say it's THE carb for a 340 but I've got another car that's a toy... the 340 doesn't have to be right at the top of it's game, I enjoy the drivability instead.
