perhaps not on this forum here , as i have seen Panteras "for sale" with the Edelbrock carb..... yes, i studied the charts for jet/rod calibration and ordered a set to play with...first remark was that the charts propose a combination jet/rod which #'s are not in a calibration "set" ??? so i've ordered a set plus additional some rods....i've got already a better performance by taking the secondary jets a step greater as out of the box....( drilled them a bit larger ) and now waiting for a calibration set i was thinking of grinding a flat side at the "rich " rod part....as it's all about square inches "jets" openings obstructed by square inches "rods" material .....to calibrate the gas flow.Is there a explication of why a Holley should make better performance compared to the Edelbrock ? Myself had the choke tower grinded off on my Holley and didn't needed it : just a few pedal pumps , start the Corvette and only needed a few seconds to help reving before i had good idle....perhaps i don't need all that choke equipment on the 351C either ... should experiment with it ....even open that butterflie/tunnel stays there as a air "restrictor"... ???
Ok, no big deal ...but i like to play with it to see if i can gain some HP's....
..and yes, i should instal a wideband A/F gauge to get it on the right spot.
