Holley tuning??

what are the jets? do your primaries about 70 and secondaries at about 74-76. but all in all, change to a vacuum secondary. put the eddy back on and trade that DP for a VS. in an auto, check your vacuum reading in gear, about 2 in. below. I run a 360 Mp short block 10:1, eddy heads, rpm AG intake, holley 3310 750VS with a 2.5 power valve, 70 primaries, 76 or 78(?) secondaries, light yellow spring with a quick change spring kit and a proform main body. from a standstill, i can put the hammer down and hit about 5200rpm and get sideways and take off like hell. I need more rubber back there. so either get the eddy back on or trade the holley, your engine will love you.
