Hello,
I saw your spec for the KG6 cam
I was wondering, the 4,3mm on the intake valve at TDC, is that with 0 valve lash or 0,35-0,40mm ?
I assume stock rocker ratio ?
Yesterday I checked and got 4,85mm with 0,4mm lash and KG roller rockers (1,6 ratio), recalculating for stock 1,5 ratio that would give 4,55mm. This leads me to think my cam is a few degrees advanced. Is my thinking correct in your opinion ?
I also notice very weak vacuum (no leaks) and in comparison to the 10,5/1 C.R (which is probably too low for this cam) a low cranking compression of 145psi on all cylinders (the engine is overhauled and has only about 10 running hours on it)
Best regards
Stefan
