Are they to be placed directly next to each other or furthest apart. I didnt take apart this engine so I'm in the dark on this one.
Thanks

Here is a link to a Shop Manual for the second series '55 235ci. It should be the same as for your truck.

If you install the cam with the marks aligned with each other, the next turn of the crank will have them as far apart as possible. Always turn the engine twice to make sure you haven't made an alignment mistake on the tooth pattern.
Exception to the rule- - - - -I assembled a Ford 3000 tractor engine once, with a very complex timing gear set with about three idler gears for accessory drives. Everything was timed with punch marks. I rotated the engine twice, and a couple of the marks were out of time. Tear it down and reassemble- - - -four times! It turns out the idler gears were made with a "hunting" patern to equalize gear tooth wear, and the timing marks aligned again after 96 turns of the crankshaft!

There is just not an absolute clear pic of the timing marks and how they are orentated. Better to ask questions than to build a perfectly good paper weight.
Thanks again,
Rick.......... | | |
