Good afternoon all,
some more questions if you don't mind regarding performance changes:
as a reminder..
948 block bored 60 over,
1098 head that has been ported and milled to 22.6 cc combustion chamber,
1098 small journal crank
1098 lightened and statically balanced rods
Will a 1098 piston end up with lower compression due to pin-face
height differences?
Will a 1098 piston (of appropriate diameter) end up being a "pop-up"
piston?
Can I measure the lobe height minus the lobe height opposite to
determine lift on a cam (Are the rockers a 1:1 ratio?)?
When you look at where I am going with this what jumps out at you and
screams "NOOOOO!!" ?
.. and I can not find this info in Vizard/Haynes/Factory manual.
Vizard lists all sorts of info on aftermarket stuff but little on
stock stuff that I can find
Thanks again!
Lester
