i didnt see until now cams on the cayote?
and why all chevy owners install camshaft but ford owners don't!! >>there is difference between ford engines and chevy engines???

Who said people don't install cams on their mustangs? you can do that in a garage in 2 hours they are right under the valve covers.

You also have 2 or 4 cams to buy as opposed to 1 GM camshaft. It isn't cheap, but it's a bit easier with the OHCs. Cam shafts are so readily available for GM engines now and with them still using pushrods, you can find almost any grind you want.

Ditto to what Automagically said. Furthermore, the Coyote is a very new engine so you aren't going to see many aftermarket parts for it just yet. And lastly, with the programmability of the TiVCT system, we will probably see custom tunes do some of what camshaft swaps did in non-VCT engines.

not much of a 'mustangdoctor' friend...

As aftermarket developmetn continues for the new engine, expect to see many grinds become available. Shoot the aftermarket is just starting to learn how to make power on cam swaps on the 3V 4.6 motors! It can take a while.

But it is something that happens. Plenty of people swap cams in their OHC mustangs.

This was the other point to be made about the modern OHC systems as opposed to the OHV.

Is there a difference? Yes a big difference in an OverHead Cam (5.0) and an OverHead Valve. It's just cheaper and dare I say easier (unless timing chain sprokets etc are not removed on the DOHC motors then it's the other way around and just cheaper) on an LS (GM). Dunno never physically changed one on a ohc V8 "yet". Done a couple LS cam swaps, much easier than the old Small Block Chevys.

$300 Camshaft and about 2 hours as well "if" just replacing camshaft and not accompanying springs. Vs whatever 4 camshafts cost. There's several cammed OHC motors out there, hell one right down the street from me (4.6 though not 5.0).

Close call right there Pat !

JPC has cams in their 5.0. They are currently testing them out. It's a mild regrind of factory cams and will work with the stock springs.

Cost? $900...

the hardest part of pulling 4v cams is the mid tensioner. the chain that lin ks the two cams has a tensioner that blts to the head and has to be removed to get the cams out. the cams come out as a pair. a timing chain holder tool keep the main chain in place. i would not recommend a novice change 4v parts.

1. remove coils
2. open valve cover
3. remove all of the followers
4. apply chain holder tool and lock it, mark timing chain/gear with paint marker.
5. remove main chain pulley and chain, loosen the exhaust cam bolt
5. apply pressure on mid tensioner and collapse it. use wire to lock it closed.
6. remove two bolts and remove tensioner
7.remove all of the cam caps and place in correct order. they cannot be reinstalled wrong or it will ruin the head.
lift the cams out together and place chain and gears onto new cams
reverse.
use all new hardware and follow tty procedures.

thats a basic procedure.it does take a bit, but its not hard to do. there might be a few details with the vct sensors.

anyone know powerlevels yet for the comp cams

JPC just got their cams in. it will be a while before we know. you figure their car makes 445rwhp with the heads and they will get another 30 i bet. the stock intake is ruining power above 6500. its going to be hard to get real gains with it.

ace22

JPC just got 507 rwhp with stage 1 ported heads cams , boss intake and headers. Of course there are other mods but those are the meat and potatoes of it cant wait to see stage 3 heads with upgraded valvetrain and 8000+ rpm;0

The ECU doesn't have any programming past 7800 RPM. If the engine exceeds that, it will go into limp mode.

I susupect that the custom tune would take care of that.

The new cams would require a new tune more than likely anyways as it would be using the variable cam timing differently than stock (I would assume)


anyways, these cams/heads/intake/exhaust, etc all sort of build off of each other synergistically. One component alone isn't worth much but adding the ported heads all of a sudden make the intake flow a lot more = more power.. same with different cams and higher flowing exhaust, etc. I'm probably preaching to the choir here though
