I used a degree wheel & cam bushing kit for the smallblock chev.
Same chain & gears as 4.3 GMC.   I now remember an article in
HotRod, where they said to adjust it for the highest cranking compression.
The thing seems fast, between 15-20 lbs boost, it pulls as hard as ever.
I need to wait for the tracks to open in NE Ohio to know muck more.
Butt-dynos are sometime optimistic..
