Gene, this would be good historical info to be included on your web site.

ok ok, lets give this a try. This is what I have so far.
For example the 73 manual says that the front axle is torqued to 110 ft-lb.
The 75-76 says 140-280 ft-lb. The 77-78 says 110-140 ft-lb not to
exceed 280 ft-lb.
The 75-76 manual says the front end alignment should be 0 to -1/4"
(toe out). The 77-78 says -1/16 to -3/`6" (toe out).

Another inaccuracy. On page 6Y-45 of the X-7525A manual, distributor
rotation is
listed as counterclockwise. On pages 6Y-33 and 6Y-34 of the X-7725 manual
it is
listed as clockwise.
Dick Paterson in one of his seminars stated that distributor rotation on all
Oldsmobile engines is always counterclockwise. paul

| 5 6 |
| 7 8 |

Since this is from my notes, I probably wrote it there because there is a
mistake in the FSM.

My notes show the error to be in the distributor cap plug wire numbering,
since my 455 firing order picture is correct, as stated by Patrick.
(p.6Y-50, 75-76 M.M.)
Manual diagram shows plug wires 3 and 6 reversed.
Should be wired (in clockwise sequence) 1-2-7-5-6-3-4-8.
