OK, so its on and it runs, I installed 36's instead of the 75 iab's as per Holley for a 2 corner idle. Its still pig rich at idle. Went back to the 75's and no real change. Almost as if the Carb isn't responding to the change.
Timing is at 26* initial, with an additional 10* of vacuum.
36* total. On test drive its unreal, snappy, power everywhere, no bogs stumbles etc. Part throttle in OD it pulls clean from low rpm etc. So it seems right across the board, and is def making more power then it was. Any suggestions from anyone who has done the HP or proform upgrade to help my idle? I'm a few weeks at least from getting a wideband so i can't make drastic changes but do wanna clean up the smelly idle.
Here is the set up.
355, 10:1 comp
Pro-filer 195 heads.
4779 with HP main body upgrade with screw in bleeds
Primary are 75 hsb and 36 iab
Secondary are the same.
