    Which row? It kinda doesn't matter other than cylinder numbering.

    The cylinder rows are labeled A - D, banks 1 -7 and the firing order is shown for each bank.

    R-4360
    were we talking a -59B?

    so we're talking time of the cam to rotate?

    fireing order is as follows. each cylinder to fire will be located four banks clockwise from,and 1 row in front of, the cylinder which has just fired. if the cylinder which has just fired is in the front row the next cylinder to fire will be in the rear row. a1 b5 c2 d6 a3 b7 c4 d1 a5 b2 c6 d3 a5 b2 c6 d3 a7 b4 c1 d5 a2 b6 c3 d7 a4 b1 c5 d2 a6 b3 c7 d4. 4 mags or 7 mags depends on dash. # 3was answered already. duration is 276

    If you start at 64 degrees btc, and then you say there is 76 degrees abc.
    That is 64 before top center, and then 76 after bottom center, what has happen to the rest of the degrees rotation inbetween?
    180 degrees has been left out. Duration is total time open from start to end. 276 ? What dash number?
    What are the open and close points?
    The given numbers must be at actual lobe, and not including valve lash, which will of course decrease the actual open close points.
