Even though I use Edelbrocks ultimately the lack of pump shot and secondary opening does seem to slow 60 ft some what. But when $ are compared I didn't find it cost effective for my program to pony up $1600 or so for a pair of modified Holley's to gain approximately .05 in ET. Doug
if your running 750's then there's probably a way to open up the accelerator pump well for the larger volume 800 pump.
