    You can tell the Lamborghini V12s as the intake tracts are between the cam shafts. One day I’d like to learn why they did that.

    All about airflow and packaging. Hard to beat a "line of sight" path. And the closer you can get the intake valves to the bore centerline, the larger valve you can fit in the chamber.

    Early Ramcharger's C/Altered car.



    Chrysler used their "longer is better approach ... Lots of down then up then across .. and they did nothing about where it really matters .. the turn just before the valve head.



    Conventional BBC head has a low port with a sharp turn ...



    Water ports are the same on both heads , but look how much higher the intake port is. 200 -300 more horsepower .. easily. But it does take a very long valve stem hanging out in the port . Makes the head of the valve whip around like a flag on a windy day ..


    Even the exhaust side shoots for the moon ...



    Yamaha leads the pack in airflow development. Line of site , like the Lambo . Centralized intake valve placement and to keep away from having to "bend the air" around a short side radius , they just put in a third intake valve . A bit ahead of it's time .. Americans have accepted 4-valve heads , even 4 stroke outboards with hokey lookin intake manifolds .. might as well accept the 5 valve as the powerhouse head of choice.



    Look how high the port is from the deck , and the angle it assumes . Could easily fit in the valley of a V configured engine , and have a almost "straight down shot".

    Yep, instruction decal for Merc power trim. Back in the day when the oil reservoirs were made in aluminum and not the molded plastic junk they are today.
