Funny you bring up cammer heads...that's in a twisted sick way i was leaning!! that being said, i do know that the cammer had some higher rpm problems do the ohc design. maybe ford was trying to much with semi-hemi combustion chambers and overhead cams...BUT, i have an idea! -and it just may work.
cheers,
ps: if you can remember the library name of those blueprints i'd certainly buy that for a dollar!
