That 300 is AWESOME! I have always wanted a old 40's or 50's truck with a totally fixed up inline 6.... Ever go to inliners.org? Those guys (some of them) are putting turbo's on them and everything and smoking small blocks!
Seems like I heard about someone that took 2 V8 heads and split them, then some way machined them to work on a 300 I6. Maybe it was only a dream, but it seemed like 460 heads.
All i can see is making some boost and a huge dent appearing in the hood as the huffer tears loose the small tits that offenhauser calls mounting lugs.....
Been there and done that and rewelded them after fifteen foot pounds of torque
