Yes, Bosch sensors, and did the tetsing at a local car dealer.
Idle approx. 12.3
Cruise 14.6
Wot 12

I know the Holleys is said to be rich at idle, but so much?

Know about the MSD timing master, perhaps later hoped to get this going without. My retarder system function allright for now. (when ignition got the right adjustment)

I would think you can do some adjustments/mods to your Holley to get the idle A/F mixture a bit leaner, drill out the idle air passages a hair bigger?

Anymore recent floggings?

Plans to drilling...seems to be only way to go...... Rest of the setup function great, now another pulley on the eaton are in the mail, and the supposed 5,+ PSI are in reach!
Unfortunately my waterpump break down, and more adjustment must wait for this to come!

Then everything seems to be nearly in order, PSI boost 5,8, still got to rich mix at idle... but.
Heres a little video of engine running!:

Very cool!

Is that a 6 rib serpentine on a 8 rib pulley?

Yeah! No trouble, no skid, no slipping! Ainīt got a lot of space to my radiator, and each inch who could be excluded, than less work of changing/reworking parts! 8 rib pulley is only at the Eaton, the rest, at crank,idler is 6-rib.

Iīve got my new AFR system now, and its down to 10.3 - 10,5 at idle, approx. 14,6 at cruise, and 11.6 - 12. at WOT. Got some ideas from an old carb guy, and gonna check them out to see if its help...
