It looks rich from 4k to redline, but definitely safe. You should see somemore mid range power if you lean it out to about 11.8:1. That should be easy to correct.
Yeah, you're running pretty rich from about 4,200 rpm to 6,000. Dipping into the 10's is safe but you can definately pull some more power out of it if you get in to 11.5 to 11.8 range.
looks good to me! maybe a i bit rich from 5-6 but i personaly still like low 11's on a/f.
my a/f also slopes down from lean to rich liek that. i prefer to keep it that way. when racing youll never see those rpms unless u punch it on the street in those rpms. and u wont be there long enough to increase cyl temps to high.
running lean down low like that builds nice torque numbers. look at your?
look at mine with a ported blower which usualy drops low end torque
it looks okay but get that line straightened out and hit that 475 mark! :beer: I'm hoping to hit close to 475 wih just my 2.81 on the next dyno visit. epper:
