Gee I have a customer that has a pair of the 800 AVS carbs on a Stage V inline intake and fairly mild hemi that only made 845 on the pump and runs 9.50s at close to 3600 lbs. No gurus, no secret voodoo magic, out of the box and we changed the jets a little. Just junky street carbs though. Alot of the NSS guys run them on the wedges and the hemis due to class rules and they crack off plenty of 9 second passes all the time.
