Pedestal mount rockers

[skipped_link]

I've searched & mostly just found threads on adjustable rockers,

I am running a fairly stock EFI 460 with the F3 fuelie heads, the only thing not stock about this engine is the headers & this cute little cam shaft,

This was supposed to be a temporary engine, but the thing runs so good I don't want to take it out,
This winter I had a couple extended higher rpm attacks on some snowy hillsides & drifts, one of them resulted in a push rod shoved through a rocker arm, I would like to upgrade these parts to prevent this from happening again,

I was looking at these rockers,

I guess the question is simple, are they worth the money for what I am doing, or would the $140 Comp cams high energy stamped steel rockers be just as good for my simple application, I know the roller rockers are by far better, but is this application worth the money?

Anyone have experiance with the FMS pedestal mount roller rockers? How was the fit & finish?

Yup seen that thread, they are adjustable, (not needed for my application) & considerably more money, they do look like a nice product, just not what I need,

The CompCams magnums do not exhibit good geometry. Most low cost rocker arms use a B.B. Chevy geometry based rocker arm.
Be sure to use a DEDICATED Ford rocker arm like the bolt-down, non-adjustable roller rocker arms available from FRPP. There are others out there also.

If these rockers have BBC geometry then they did a lot of work to go backwards,

I know what you are talking about with the stud mount rockers, but I am working with the pedestal mount rockers,

So, with that said is this rocker

Worth the $230.00 difference

over this rocker

I'm sure there are cases where this is a hands down silly question, but for me with a virtually stock engine, with a little cam & headers, livability is the most important,

With that said if I saw a horse power gain of 10-15 hp through less friction, I would probably spend the money, (to a stock engine 10-15 hp is noticable) but if the HP gains were very minimal & the stamped ones would take the beating just as well, I'm all for saving over 200 bones,

Time to go search HP gains with just roller rockers,

Those rockers you are looking at are simply repackaged, stock, production rocker arms. There is no point in going to them unless your present rocker arm assemblies are worn out.

Scorpion makes a nice pedestal mount rocker at a reasonable price. Made in the USA and a lifetime guarantee. I've used them on a few engines and they set up nicely.

my engine has the same cam also, but uses the E7TE heads, which i intend to put larger valves and light porting on.

What is it that you unexpectedly are so happy about with this engine?
Does it pull well form idle and up?
what's the weight of your verhicle?
curious about the predicted 10-15 horses gain, as i have the same question...
Would be nice to know.

I've stuck one push rod through a rocker, & the one next to it was cracked, (almost ready to go)
I did not know that the Comp rockers were repackaged stockers, I thought I read some where smoe one made these rockers with a better material & hardening process, I'll have to look into this more

I've seen scorpion products, & seen people that are pretty happy with them, I did not know they made a pedestal mount rocker, I'll have to check it out,
Thanks,

I've worked on & driven many ford vehicles with the stock EFI 460 (I work as a fleet mechanic) I've run acrossed a few that were really good runners, but for the most part with little to no load in the same vehicle, say a 94 f-250, a good running 5.8 would run right with most stock 7.5 (460), hook a trailer on & that does change things a bit,
So when I removed the 501 to install the 460, (mostly for the EFI & the 501 was simply overkill for power) I was ready to except the stock 460 being a bit of a slug.
I did a lot of research on this forum & found people opinion on different EFI cams, exhaust ect. & based the build from there,

The things that exceed my expectiations are,
1) Power, the thing seems to make respectable power everwhere, I know it's no race engine, but will scoot right along, My buddy really wants me to put the engine in a pickup to try it, he thinks the rig it is in makes the engine look good,
2) I don't know what it does for mileage, but I can go 4 wheeling 6-8 hours, Mostly cruising at low speeds, but there is plenty of flogging on it in a day, In 8 hours I'll usually go trough about 8 gallons of gas, again this is slower speed stuff,
3) dependabilty, other than the rocker incedent, I've done nothing but change the oil in this engine since setting the timing & breaking in the cam.

Does it pull well from Idle up,
Yes, deffinately
what's the weight of your verhicle?
My vehicle weighs 5500 lbs,
The 10-15 HP was just a number I through out there, I honestly have no idea what the gains would be,

Here is a video of the vehicle, if interested,

I still have a brand new set 2 or 3 yrs. old for BBF. I needed the kind for 7/16" stud instead of the 5/16". I never called them back to ask about an exchange, I wanted them right then.

the stock rockers should handle the cam you have with no problem. Do you have coil bind or retainer to guide interference issues? Do you think by chance that during one of those higher rev moments you had the valve float and the pushrod came out of the cup of the rocker arm that caused it to hit off to the side of the rocker cup... which would cause way too much lift and then prompt coil bind resulting in busted/cracked rocker arm? Maybe it just had some valve float and the lifter pumped up enough to cause spring coil bind and that was the issue. Just tossing out some ideas because sub .550" lift shouldn't be a problem on stock rockers so long as the valve springs aren't over 300lbs open. I wouldn't trust stock valve springs above 4500rpm.

Actually we have the valve springs jacked up a little bit, I could not say what they are over the nose, I know they are not real nasty as longevity & the use of stock parts was always part of the plan. If this thing has ever floated a valve I've never heard it,
I appreciate your coments though, all are good places to look, right now I have over 100 hrs on the engine & the only problem so far is one broke rocker & one that was cracked, & to be honest I have no Idea how many miles were on these rockers when I installed them, could have been several hundred thousand miles, it may just be times up for them, I would just like to make sure it does not happen again, no matter what rockers I go with I will double check everything up top, I did it while assembling the engine, but it would not hurt to check again,

Does any body see any gains by going to the roller rockers, or would the gain be so minimal that I would be waisting the $220 price difference?

I plan on ordering this stuff tomarrow, so any info would be very helpfull,

Are you posting these up for sale?
