bore 75mm
stroke 90mm
A little short in stroke I think but close.
I don't know what the valve Dia is
but they have 6.9mm stems
I have a burnt exhaust valve
it's 32mm across the top, but I'm
not sure where they measure the
dia at
, Intake valves are larger
sorry I don't have any of these.
The cam I have has been re-ground
and I don't even know the spec but
it's around .400 lift like .423 or some
oddball # like that, it is the mild grind
from Engle Cams in Santa Monica Ca.
and looks like a Pinto cam in lobe design.
If you could bore the block 3mm and stroke
to 94mm (a 2mm Change gives double)
you would have an 1.8L (1796cc)
MMMMM........1.8 Liters of pure raw power......LOL
Ya it's been a dream of mine, stroker 1.6L Kit
for big torque power increase.
