measure 26° at idle , 800 revs
going to 36° at 3300 revs
and with 5000 revs i measure 38°

i don't daire to go 6000 ??

wondering if it is going up to 40° ?

Experience is that the car runs strong up to 5500 revs and somewhat dys around there...
Ignition ? fuel starvation ? or can it simply be the cam design ?

according my documentation with the car i may expect the cam is a Crane Cams 133132, grind #278 H10.
