EMOP is 121degBTDC and IMOP is 121degATDC. Both cam profiles are 242deg period from top of ramps.

 

Thanks all for the imfo ,will use the cam setting gauge to set up . I will fit a degree wheel and a dial gauge on the respective tappet turn the motor and see what MOP is indicated. what raised concern about setting up was the flats machined across the face of the cam.
from what I can gather ,these flats are used on the v8 motor when doing the cam timing. I cannot see why they are there for the 6 cylinder motor. The cam specs in the workshop manual are for normally aspirated motors only, no mention of the SC motor. Hopefully I am not
going to bend any valves .Will keep you posted .

 

The flats on the inline 6 are for the tool but in reality if you were off by one tooth the flats would be obviously off from each other

Have you installed the upgrade tensioner that traps Hydraulic fluid to prevent startup rattle ?.

Motorcarman ( Bob ) has some oil viscosity recommendations on this mater that I can't recall as well as how I lined up my cams but I've seen them off after tinkering by others on other engines

The procedure on the V8 is alot different from what I understand

My dream is a externally mounted VVT If I can come up with a realistic design and controlling Maps in the modified ECU or to just directly tie it in electronically to the RPM signal with a separate VVT controller

My issue is the brittle metallurgical property of the existing cam and the coupling of the additional shaft
