<VV> 1965 GM manual (page 6Y-19,Fig 8i) Plug firing order

[Charles Lee]

Craig and JR :

That's what I thought too - that I was 'miss-tracing' the wires ? 
It looks like I traced them right, though.

Most of the wires look to be going to the wrong terminals, not just #3.

I colored them in to be sure I was tracing them right, and now it IS
clear that the figure is wrong (in my edition, IMHO).

I think this figure therefore shows the wrong firing order for some
reason. 
(This error seems to have been corrected in later editions ?)

Apparently, #1 can be anywhere, as long as the CORRECT firing order is
followed ?  
So, ANY position should work as long as it's 1-4-5-2-3-6.

But to be 'Pebble Beach' correct, #1 should be closest to the rear panel
?

I thought that this firing order might be valid in some other engine, so
I made this diagram to see if it made any sense :

This was not supposed to be this hard !

Thanks for the lessons !

The diagram (8i) in my 65 manual appears to be "correct".  It is also an

exact match for Fig. 8-61 in the 1961 Shop Manual.  It looks to me like 
your coloration of the diagram on the scanned image misinterprets the 
Manual's diagram, although I could see how that might happen, the 
diagram not being really clear about the routing of the #3 wire.

The firing order, and that is really the only important thing here, imo,

is 1-4-5-2-3-6. You will also find it stamped on the fan shroud under 
the plug wires near the standard dipstick tube location.  You'll have to

custom grind your own camshaft to change it and have the engine run 
properly.

The classically "correct" distributor orientation is with  #1 at 6 
o'clock, to the rear of the car with #1 and #2 lined up axially with the

engine -- this puts the dist cap screws at about the 5 and 11 o'clock 
positions, and the advance can near the coil.

The Forward arrow in fig 8i in the Shop Manual "correctly" points to the

front of the car.  The arrow in the .jpg appears to be "incorrect".

However, it is also my opinion that unless you are trying for 100 points

at Pebble Beach or such, it doesn't make any difference how you wire the

cap if the wires will reach.  Regardless of distributor orientation, 
there is a point where when the points break contact near TDC, the rotor

will point near enough to a dist cap terminal that you can put your #1 
wire in there and follow clockwise with 4, 5, 2, 3, and 6 and it will 
run.  Some will call me heretical, but so be it -- such is the mechanics

of the motor, and thus the quotes previously for "correct" and
"incorrect".

Drive On!
