New Chev Firing Order

[Bill the arcstarter]

It was written:
>>      While working on this 99 Chevy truck I found they changed the 
firing
>>order from 18436572 to 18736542......since it is coil on plug I only 
found
>>this out by checking the camshaft....does anyone know why the firing 
order
>>change and is the 98 vette the same???????
>>-Carl Summers

I heard some story about ignition cross-fire inside the distrib.  
Something about the adjacent cylinder (on the distrib tower) being on 
the intake stroke accidentally firing instead of the one under 
compression. Perhaps the firing order was changed to reduce this effect?

Just a guess.
