the guy at holley tech stated the 9381 has no changable air bleeds and has a old school fuel curve, the nascar 830 would be flat on the bottom end due to the circle track fuel curve.
he suggested the 82851 850 street hp?, i think blykins had it right and get a custom carb for my paticular needs. i like some of the aftermarket features like the billet metering blocks the sight glass for the float level, billet or stainless t plate. i need a vacuum source for the pvc, would also be nice to have a port to hook up a vacuum guage, i have not dropped the motor in yet so i dont know if i will have any height issues to run a 1 inch spacer.
