The build specs are of coarse 107 rev performance 10.5.1 pistons stock heads reworked to get the cc down where needed larger valves springs and shaved .030 to help get the squish where it was needed. I also run a gear drive with Head quarters 575 cam . The intake and throttle body are Kurayakyn wild thang and a rolland sands air cleaner with 2 into 1 D&D pipe with a powercommander to run it all. And yes it runs good but i pull a trailer two up and would like to have more? I guess I should just be happy with what I have already got? I also forgot to mention the normal fueling pump and cam plate.
Not all that much different from mine actually. 50 mm TB, Mackie 598 cams and headwork to mate to Axtell's cylinders and pistons. Headwork and other bits to have CR at about 10.25:1. It's tuned at a bit better than 120/120 but did so in February. Picked up a teeny bit of detonation later that year and tweaked it down a bit. Ended up about in the mid teens and upper teens.
Mine comes in early enough even if I jacked it up more I wouldn't bring that much of the gain in early enough to really be a big deal doing things like pulling the Bushtec down the highway or playing in the mountains. I could get more out of it. Even in its current configuration there is more if I wanted to tune for it. As is she runs great and comes in well very early. Would take some significant changes to get more and get that addition in early enough I'd notice it for regular cruising or pulling.
