Morning folks
 
Does anybody know the fore and aft displacement of the left/driver and right/passenger cylinder banks? 
I'm in the process of fabricobbling a dual exhaust system and ,whist under the truck, noticed about a 1/2" - 3/4"  difference in the pipe length so far.
I suppose it should be obvious really that the left and right banks are not directly opposite. The old brain box is slowing as the years slip by.
Many thanks
