Well, I just got linked here so it's a little late but I figured I'd reply.

I don't have dyno numbers, and it's not a truck, but I have tinkered with this on an f-body with an L03 (305 TBI used in the late 80's, early 90's, same one that is on the trucks). I custom made a spacer out of 1" hardwood (soaked in fuel proof dope) and a 5/16" thick injector tower spacer and actually saw .4 at the track, that's a big improvement. I suspect that part of it was more airlow, and part of it was getting the injectors up higher resulting in better fuel distribution.
