Well for years my DP 750 holley what i thought was a 4779 turns out to be 6109 tunnel ram carb after Rickster looked up numbers in holley book!(thanks Rick) I was running 76 primary and 84 sec. jets on 9.8 to 1 327 with vic. junior and 1 inch spacer and ported twisted old trickflow heads. Rick came up with 75,76 stock jetting for this 6109 carb so i jetted 72,74 on this single vic intake and took her out and car seems to run smoother with what seems to accel faster at 4 to 5 grand but as we all know sometimes seat of pants fools Ya. Any carb experts here have any advice or experience or set me in right direction OR if i may be in danger zone!!!! Thanks in advance for any feedback. Car has run best of 12.2 with steet BFG touring radials and 11.64 115.5 with hoosier QTP and 5 speed. thanks again, AL
