i finnally had hippo help me to respond to your group i am not good at
computers.i have been in the motorcycle industry for 38 years and
have been an instuctor years ago at MMI. i own a sunnen machine shop
this is the same equipment that harley factory uses in there engine
rebuilding department.one of my part-time employees is a retired
genral motors enginneer worked on vortec head project.he also spent
a week at joe mondellos school of cylinder head porting. we spent
over 6 week and are still updating tc88 and evo cylinder heads.
we developed the vortec heads for tc88 and evo engines.a vortec
is designed to increase torque which i feel harley engines need.it
was hard at first to weld up an intake port and increase air flow-
but it happens. besides increasing air flow it really increases air
velocity. i feel that harley is on the right track with there httc heads
but disagree on combustion chamber design,we all have our opions.
there cnc heads are pretty i have seen but have not got to flow test as of yet.they did not cnc the combusttion chambers. i will keep this board posted when we do.i believe in mild cams and10.1/1 compression ratios
my objective is to build torque engines.if there is question feel free to ask
be patient some times to get back to you.
thanks short-block charlie
