Turbo 440 duster

Holy crap! 839 HP @ 5716 rpm and 871 ft/lbs of torque @ 4339 rpm! Dam! And that's on a chassis dyno too.

Very nice workmanship and be sure to keep us updated. I would think that you would be using a cam with the LCA in the 114 degree range, would I be correct? Also, is there any particular reason you are using a mechanical cam verses a hydraulic roller? It appears that all of your power would be in before a good hydraulic roller would float and you wouldn't have the maintenance issues.

Again, nice work! Oh yeah, did you TIG or MIG up your plumbing?
