ok thank you. I was hoping for a universal mercedes v8 standard vut they do change, or info I got is wrong. Are cylinders numbered odd-even (1-3-5-7) passenger side? or straight 1-2-3-4.
I did find v8 crankshaft design to be identical to that of GM. I will even use the same drawing to animate the mercedes, I just need to get common firing order and cylinder number placement to note further differences. I will be startled to find out if they aren't.

The #1 passenger front side, going backward is #2 then #3 ect. Front drivers side is #5 ect. Cheers

Ok, thank you very much. A bizarre question to most I'm sure, but does it run clockwise or counter-clockwise?(I shamefully can't find what I need on the web)?

Clockwise looking from the front of the vehicle towards the rear. Mark
