The Coyote VCT and how it works.

[LarryJM]

I only lived a few blocks from Yanko Chevy where I grew up. Yanko was a small town hole in the wall dealership near a drag strip called Pittsburgh International Drag Way where Grumpy Jenkins was racing one bad ass Chevy II with a 302 in it. In any event, I remember them talking cams as advanced and retarded and then lobe split from 108 degrees to 114 and anything in the middle. As a result, they can take a stock L82 cam used from 1957 to 1982 and play with those 4 specs and still stay stock. I am sure Ford realized that if you split the cam in two and put cam Phasers on the end, you can adjust at will those specs. Make it smooth with high torque on one end and high rpm and rough idle on the other. Thus a Ghost Cam. I guess you could lock the Phasers and design the engine to one RPM range. For sure the Gen I engine has different Cam and Phasers then the Gen II. So a Gen I engine is not interchangeable with a Gen II Coyote Engine as far as the ECU is concerned.

YENKO is the correct name of the very famous dealership and the namesake of cars they "modded" back in the day. I'd think someone growing up a few blocks from a dealership with a famous name like that would at least remember how to spell it correctly.

It has been some time. No doubt about it. It was a Hole In The Wall small town dealership with big pull with Chevy and Bill "Grumpy" Jenkins was always hanging around. Jenkins was a very big name in Pittsburgh. I was just a teenager and really into Mopars.

Is there a question here? There's certainly no tech info.

Sorry, for a minute I thought they called it Chit Chat.

 

[ox white]

"Mustang Chit Chat". Not "old fucking chevy chit chat".

 

[LarryJM]

I thought it was 302 Chit Chat and getting them to spin at 8000 rpm.

https://en.wikipedia.org/wiki/Variable_valve_timing VVT tech has been around for a LONG time, various approaches. I had a failing hydraulic phaser in a 4.6 with only 45k miles on it - not that uncommon, not a great design from Ford. http://www.enginebuildermag.com/2015/03/the-challenges-and-opportunities-of-variable-valve-timing/

I bet a set of Coyote heads would do wonders on a 5L flathead block.

LarryJM has to be a troll. That or a moron.

 

[LikeabossTM]

Either way, definitely ignorable. I just can't be bothered with the random inane thought experiments.

Lots of interesting things about the 1932 V8 and V12 flatheads.

I'm partial to the LS engines - they don't need complicated newfangled vct to make power. Simple design and a nice idle to boot.

 

[LarryJM]

Then there is always the Hellcat. Although everyone likes the song Hot Rod Lincoln with it's V12.

I'll never get that 3 minutes of my life back...
