    ERR5924 Cam Timing

    I am putting an ERR5924 into my 3.9 but having trouble finding the timing specifications for this particular camshaft.
    I have come across 3 different sets of figures, all purporting to be for the ERR5924.


    1. Inlet opens 32 BTDC, closes 73 ABDC. Exhaust opens 70 BBDC, closes 35 ATDC. Duration 285/285 LSA 109
    2. Inlet opens 30 BTDC, closes 75 ABDC. Exhaust opens 67 BBDC, closes 37 ATDC. Duration 285/285 LSA 109
    3. Inlet opens 24 BTDC, closes 52 ABDC. Exhaust opens 62 BBDC, closes 14 ATDC. Duration 256/256 LSA ?


    Whichever of the three it is I will need to know the inlet valve lift peak at x degrees for the intake lobe.
    From this x degrees I can time the camshaft with the Intake Centerline method. I am not sure from the above timing numbers how to calculate the degrees at maximum lift for the intake, can someone with more knowledge than me help work it out. Or is there a simpler method to time the camshaft correctly?

    I usually build Holden V8s and use the lift at TDC method, I cannot find the lift at TDC anywhere for the ERR5924 cam.

    I put the camshaft in today and measured all the timing events and compared them to the list. The figures I got turned out exactly the same as cam No.2 in the previous list I had posted.
