One thing I'd do to get a feel for how "off" the cam could be, (installed position and size)..... Is do a cranking compression test.
What's the elevation where you race?
And what are the performance numbers for the truck?
Thanks for the advice! I will try and do that soon and report back.
The track elevation is 702ft
With the old cam it went 7.57 @ 89.0 with a 1.663 60ft. Last night it went 7.77 @ 89.9 with a 1.759 60ft. Also last night was a "street" night so track prep was dismal to say the least.
