Re: Shaved Head response/question

["Ken and Susan Buck" <phillyscca@mail.enter.net>]

You and I both know that adjustable cam sprockets are illegal in DSP  
:^).  JUST KIDDING !!!!!!!!!!!!!!!!!!!

We have one offset keyway at the shop.  It looks like a normal 
spocket key, like a half moon, except the half that sits into the 
camshaft is offset from the half that sets into the sprocket.  They 
are pretty trick.  Sort of looks like it is partially sheered off.  
This allows you to retard or advance your cam timing depending on 
which way you install it.  We are looking to advance to compensate 
for the shaved head. 

I dunno the 'exact' degrees these little guys give, but they do 
indeed make a difference in the performance.  The retarded cam timing 
from the shaved head reduces low-end torque, but screams in the 
higher rpms.  The offset keyway will give back the low-end torque 
needed for good acceleration.
