[AT] Just wondering,,Cylinder numbering

[Alan Nadeau]

The only ones I am familiar with  are Chevy, International & Ford.

Chevy uses the front cylinder in the left bank as #1 and IIRC has the odd 
numbered cylinders on the left bank, even #s on the right.

IHC, at least on the 304 & 345 boat anchors used the same layout but they 
timed on #8 cylinder.  Was absolutely hilarious when I watched a GMC shop 
mechanic trying to time an IHC engine off  #1.  I tried to tell him but he 
wasn't buying it

Only Fud engine I have had to deal with was a 460 in a F-350.  Their 
numbering started with #1 on the RIGHT front and went 1-2-3-4 on the right 
and 5-6-7-8 on the left bank.  Once I figured out that if I superimposed the 
cylinder numbering locations and firing order that GM used I could treat it 
just like a GM engine.
