[AT] Just wondering,,Cylinder numbering

[charlie hill]

I once had a boat with an OMC stern drive.  It had a 302 Ford engine.
However, for performance reasons the factory had put a 351 cam shaft in
it.  Now here is the weird part.  Apparently the 351 Ford engines for
some reason related to balance do not have the same firing order as
the rest of the Ford engines.  It is more or less reversed as I recall.
If I hadn't read that in a repair manual I would have been in a mess!

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.
