    Maybe he wants to pull stumps with his Mustang

    That was my thought. If you could somehow start in 3rd gear, with strong enough gears and wide enough tires to hook up, you could theoretically get a good jump off the line. But such a car would be good for just about that, and not much else. It would probably handle like a Challenger by then.

    Given the opportunity, I'm sure they would have readily changed the block to use non-concentric camshafts or a DOHC setup, but were told not to change the block. Sometimes the design constraints don't make sense and you end up with cam lobes pinned to a shaft that lives within a hollow cam shaft.

    If the Vari-Cam is what I'm thinking of, I've already addressed it. It simply changes the cam phasing with respect to the crankshaft, but does not alter the intake-exhaust phasing.

    VTEC is a bit weird in that it adds more valves... You can't really call it a VVT solution because the timing is fixed, you change the porting. It's a digital attempt at an analog problem.

    TiVCT is exactly what were talking about. The ability to vary timing of the exhaust and intake valves independently... Twin Independent Variable Camshaft Timing... Vanos is a different version of this. Neither can be done with a single camshaft.

    Still rather have a Boss 9 (529 Cubic Inches 8.7 Liters), Boss 429 427 (Solid Lifter) Side Oiler or 427 SOHC for an engine swap, they are known quantities with cams, carbs and efi readily available. Also they have Forged Pistons, Cranks and Rods. The Coyote 5.0 3rd generation is pretty awesome too, there are a lot of upgrades one can do. The 7.3, revs low with a low redline. Bet it is designed to rev up slow too. Love to have it (7.3 in an F150), but many far superior big block for swaps in an S550.. Opinions are like engines, every car has 'em.

    You keep saying the 7.3 is the better of the two BY FAR, what measurement are you using to claim a truck engine is by far better than the Coyote. I've seen nothing posted showing this 7.3 to be bar far better, anywhere.

    And you won't. Cause the 5.0L Coyote is superior & more potent.

    Exactly, he keeps saying it as if repeating it will make it so.

    The 7.3 liter motor is better, for a truck. How many of you want to swap your Coyote V-8 for a powerstroke diesel? There are some out there that would do it, because they can! The 7.3 swap would be interesting, however I don't think we will see a mass migration to it at the drag strip.

    Exactly.


    My point was that the Vari-Cam could be (and probably was by many) considered a silly complication.

    VTEC was much more than a few extra valves in the intake tract. It was a stepwise approach to variable cam timing/lift involving cam lobes of different specs and a mechanical means of selecting which lobes were controlling the valves at any given rpm.


    Some would call any of those arrangements "needless complexity".

    The only difference I'm seeing between TiVCT and ChryCo's cam-in-cam is that TiVCT keeps the cams completely separate. Perhaps TiVCT permits a greater range of phasing, but that's a detail difference rather than any difference in basic operation.
