Nice combo.
Are the correct springs on the head for that cam. It seems a bit short on RPM.
I see you all ready went with more stall, which is good. You should see a nice drop in ET.
What is your track Alt. I just noticed your in Az. Around here, near the water, kind of, LOL in E-town N.J., alot of guys are knockin down good times with a similar combo. A slight faster. (Not raggin on ya)
