Lean idle. Rich cruise.
OK. Time to report results. 77 degrees today, low humidity. Took a nice long ride, got it nice and warm. idles at 1150RPM as usual, 13.5 AFR. Good. I do know big(ish) cams like a bit of rich idle.
Next, cruising on dead level road, 45 MPH around 2800, AFR mid 12's.
65 MPH, 3300 RPM 12.8 to 13.2.
And WOT, at a well known "test hit" spot, always between 12.7 and 13. Perfect there......
So the cruise is much better than before but still too rich. Already swapped in .062 restrictions from the .070 I put in a couple days ago. Hopefully it will respond well.
Also, I'm open to all you guys suggestions, so I ordered a 10 degree bushing for my MSD distrib. Been locked a few years but we'll see how that works out. When I talked to Dana at 4 Seconds Flat and mentioned I'm locked at 35 degrees, she read me the riot act. VERY bright people there.
Weather here looks like sh#t for the next couple days, but I will report back! Me thinks you guys pointed me in the right direction. Even an old dog can learn new tricks.
