Mike, Andy, the V8's you are comparing don't stagger the cylinders? You mean they line up perfectly opposed on either side. I might give you a cylinder, maybe a little more, but not two unless your talking about the W8. /forums/images/graemlins/grin.gif Just for the heck of it, I measured my 7.3l IDI, from the back of the engine (not the bell housing to the water puump its about 31". Anyone with the I-6 and a tape measure?
