For those not versed a few facts may be of interest.
Most V8s since the 1920s do not use a "flat" crank but a more complex one giving smoother balance. Flat cranks are used for racing as the firing order better suits tuned manifolds (and produces a more impressive exhaust sound!). Most V engines have conrods side by side on the same crankpin. But some have had one rod forked to fit each side of the other. And others use the master and slave rod arrangement as pictures (which arrangement is taken much further in radial aero engines).
Normally there is only one camshaft so a problem with sv v engines is the mix of exhaust and inlet manifolds in the V, so that heat is a problem. The Ford V8 ducted exhaust through the block to the outside but heat rejection into the water was great.
