Nate, that did turn out really nice-very sanitary. Before and afer dyno tests would be even nicer.
You do realize you are now on that slippery mod slope with your stocker!!
My last venture into multiple carbed vehicles was a long, long time ago with a 60 ElCamino and the 350 hp version of the 348 that we had warmed over with 12:1, wicked solid lifter cam, and a balance job. Ran pretty good for a rather heavy vehicle.
These days, I think fuel injection is a much better option, especially for an off road vehicle.
