Normal points type Ignition system seems to be all there and nothing hanging out side the block....all is good so far ! :wink:
Thinking about a thread that Markus did on the circular looking spacers under the valve springs ....and thought I would check this one. Sure enough it has one under each spring....doesn't seem to be a valve seal, maybe just a steel spacer to keep the aluminum from ware.
Kinda Impressed with with the valve size on this hs40, Int valve diameter is 1.079 or about 27mm, Exh valve diameter is .974 or about 24.7 mm.
So far ...so good , but here goes the side cover....:scared:
OK ..this is something that I wasn't expecting...what tha !?!? First look at a 1970 HS40 camshaft for me and this is what I see. Massive Int. lobe with a compression release ...
and a very normal looking exh. lobe.
Both lobes are cut on different base circles.....so really not much more lift than a regular cam. Sorry I didn't measure the lift....so it is what it is.
Heres the lifters, and not surprising that one is a whole lot shorter than the other one.
Int. lifter ( short one ) measures 1.321
Exh. lifter (longer one) measures 1.477
Not spots...just a paint marker...to help forget fullness ..:laugh:
Cylinder measures 2.623 at the top...piston measures 2.620 at the skirt.
Rod journal measures 1.000
