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

[J R Read_HML]

Despite what I previously said about #1 being close to the engine block (I 
was wrong), it is not physically possible to have it in that position 
because of the vacuum advance unit.

So, what I think will fix your diagram is to "move" your colorized wires at 
the distributor.  Put #1 where you have #3 and put # 3 where you have # 1. 
See if that fixes everything.

Did you look at the pictures I sent?  #1 is actually at about the 5oclock 
position when viewed from the rear of the car or the 7oclock position when 
viewed from the right side of the car.

I think that you have changed colors on the #1 and #3 wires mid-stream.  It 
would seem easy to do at the point where they are more or less bundled 
together (passing over and under one another) in the diagram.

Later, JR
