    Anyone know if the HC is a VVT engine like the 6.4?
    From what I had read and experienced for myself the 6.4 VVT dosnt start working fully till 1800 miles for engine break-in. Just wondering if that would apply to the HC.

    that could be urban legend....i felt my 392 do a bit better at around 4,000 miles.....or did i imagine it?

    at some point an engine breaks in and gets a bit better mileage, so id assume it also increases a bit of HP

    i dont know if it has ever been verified that the 392 has magic hp after a few thousand miles

    Ok good to know. I could have swore I read somewhere that they should be commended for putting vvt in a supercharged engine. Must have been fluff.

    I think people who buy a muscle car and worry about MPG, don't get it at all.

    While I agree, and don't care too much about gas mileage, having decent mileage if you stay out of it is a plus. Drove to work this morning, reset the average MPG, 30 miles on the highway, stayed around 70 mph... 23.7 as I got close to my exit. Of course after showing it to people at work and driving around town to lunch it dropped to 8.5, but was back to 14.4 by the time I got home (not exactly going easy on it).

    No complaints here.. :)

    VVT= variable valve timing, more for horespower and torque, overall driveability then gas mileage. Not like cylinder deactivation systems.

    VVT and MDS are mutually exclusive. VVTs main purpose is performance and better MPG is just a side effect. You are most likely thinkg of the MDS Cylinder deactivation that are on the 5.7 and 6.4s.

    For example, my SRT 6.4 6MT has VVT but not MDS. So I am not asking the question because I want better MPG, but was asking the question because its a long rumored myth or science, depending on what you read, that the SRT 6.4 limits that VVT during engine break in until roughly 1800 miles. (this has never been truly confirmed again but some srt engineers mentioned it) at which point the VVT works fully and you get a slight hp bump. I am just wondering if the same applied to the HC.
