I would hope a 496ci motor would run as good as my little 347ci motor did on a 100 shot, it has 150ci on it. Now as my cubic inches get closer to that 496 mark (418ci) I would suspect I would need less bottle.

Again, I am not saying you can't make big power on the BBC platform. With any NA motor, if you have comprable heads for the ci (flow enough for the ci), the right cam and combo, a bigger cube motor should make more power, period. I just see too many bad big block combos to be an advocate of the big block craze. I'm not drinking the cool aide, but then again a lot of you big block guys aren't drinking the LS cool aide.. To each his/her own. That's what makes this sport fun!!
