Larry, Sorry I missed your post earlier. That is a great chart. I know the guy that designed KB pistons. He also rebuilds McCulloch Super chargers. I'm going to enlist him but he doesn't know it yet. I'm trying to get as much lined up here before I stsrt bugging him. He's busy.
CNC, thats just what I was thinking about the head. It seems that I saw a GMC that had a front drive mag but had a cut down distributer in place to drive the oil pump.
I'm running the later small port closed chamber head on my 270 now. It has some port work done and has served me well on the street for over 30 years. It might get pressed into service also.
Thanks guys! Beater
