This has been driving me NUTS

Well, i think, if i remember your build correctly, is you have to much carb. An 800 is way to big. It may choke it. Im also not sure on the cam specs, but i know the teens like the Voodoo 403.
To be hounest, i hope you win, but i think he's goona get you. Form what youve said, with the carb, cam, no upgrade in pistons, preformer, gears and manifolds. i dont see it, This is just my opinion, and maybe i missed something. I hope you prove me wrong. Good luck
