I have heard back from YearOne, they are suggesting to swap to a carb arount 700 to 750 CFM.
Well you got the temps about right, temps during the Dyno were aroud 90, and our elevation is about 1100 feet.
have you taken a exhaust back pressure reading at full throttle?
I have no idea how to do this.
did you degree the cam in or only install it per the dot-to-dot marks?
The cam is degreed by who ever builds engines for YearOne.
what was your total ignition advance at 3000rpm?
15 degrees
what was the true F/A ratio?
Dyno graph shows about 12 (percent?) at lower RPM's moving hitting about 13 at 5500 RPM
what was the vacuum reading on the intake at full throttle?
vacuum guage reads 8.5 In-Hg not connected, connected and at idle vacuum reads 20 In-Hg, full throttle vacuum reads 29.5 In-Hg
go any pictures of the spark plugs?
I'll be pulling them on Sunday.
throttle blades are opening all the way?
I'll check this on Sunday as well.
