Hi Lon,
Over Head Cam worked OK, at over six hundred horse power, stock '67
Mustang Factory X:
http://www.popularhotrodding.com/fea...2phr_afxstang/ But, they
did break parts, that were very expensive compared to the create price
of twenty three hundred at the time:

OHC was a true hemi: http://www.cia.com.au/seale/stangeng.html Uncle
Sam, called me during those years so I didn't get to play with them,
then marriage and other things began to take priority.

Hi Dave,
Because to get the valves to point at each other in the
hemispherical dome design, the rockers have got to take some weird
angles: http://www.classichemi.com/pattern.jpg The new little Hemi wiped
it though, it'll just never develop the horse power like the engines
from the sixties: http://members.aol.com/franangrenteria/frankRam.jpg
