Waynes are stud mount adjustables w/ guide plates. Tapping for the studs is necessary.
Moranas are pedestal mount bolt downs.Non adjustable and no guide plates necessary.A direct bolt on.

They both give you the same results.It's just that the Morana kit is much easier and less time consuming to install.

Here is a pic I took while I was installing them.

Those rockers look almost identical to the 1.6 roller rockers from Ford Racing that one can bolt onto a stock 5.0 motor.

So you don't have to worry about adjusting the timing for them?

That would mean the morana 1.7 rockers would be a much easier install. I have to replace the valve cover gaskets and this would give me the extra amount motivation to do it.

Anything to liven up the 3.0....

I was thinking the exact same thing.It's all in the pedestal.I've heard that the 3.0 and the 5.0 have very similar rocker assy.
If you noticed Morana carries all the same sizes as Ford Racing.I wonder if they even have to machine the pedestals.
This was done on my DD so no time for R&D.

It seems these roller rockers have made quite a buzz amongst the 3.0 crowd, but no on seems to be talking about the cams at all. Tom Morana offers three different stages of cams for less than the roller rockers. Seems they might be worth looking into more. I don't know of anyone on the site that had run one though.

cam equals pain to install also rougher idles and probably kill gas mileage.

If you go with a huge cam you will lose gas mileage. My buddy installed a mild cam on his 06 GTO and the gas mileage was not affected at all. The idle is a bit rough but it sounds sweet and its not unbearable.

What is the cam doing different than the rockers? Isn't the main function of the cam to change the duration of the valves, either opening them wider, or for longer? Also, rougher idle, what does that exactly mean? Your truck shakes at idle, does it accelerate the same? Sound different?

I doubt they will hurt mileage. But then again I have no experience with them. They put less stress on other components because the tip and the trunion are rollerized.

You will get that rumble at idle but so what. It may shake a tad when you let off the brake and roll forward at idle but again its not bad at all. It just a slight rocking. And yes these have the same affect as a cam but just like a cam if you don't go crazy end get some ridiculous duration the rough idle will be minimal.

The 1.7 and 1.72 basically give you a mild cam without all the work.This is all you would want on a street vehicle.The bigger cam is not always the best choice on a street car/truck.
Why install a camshaft that makes peak power at 7,000 RPM when your 3.0 will never see it.At least mine won't.
The 1.7 rockers make the lift a little less than Morana's mildest cam.The 1.72 rockers make the lift a little more than Morana's mildest cam.

Mild Cam:



Huge cam:



The torque converter on auto vehicle will absorb most of the rocking with a mild cam where as a car with a huge cam will rock like crazy. The car with the huge cam can barely run on its own.

I suppose I could get a clip of my truck shaking. I went from a stock cam with .444 Intake/Exhaust with a 279/266 duration respectively, to a .512 Intake/Exhaust with a 226/226 Duration. I had also run 1.7 roller rockers on the same truck and setup. The cam gave a more noticeable difference, but I haven't been able to get to the track and find out how much yet. I know for the 5.0. the more aggressive cams require a higher idle. Mine is currently set at 950. That gets rid of alot of the roughness, and once the truck is warm, its not all that different from the stock cam.

They both sound great. The black one sounds like my buddy's ZO6.
If you play them at the same time it sounds like the beginning of a good race.
