2.9 Camshaft Prototype

[camchero]

My name is Camron, and I've been in contact with ColtCams. They say that they would be interested in making an aftermarket cam for the 2.9 I just wanted to get on and see how many people would actually be interested in this product. They say it will have higher lift and duration, and are 99 percent sure it will work with the stock computer. ColtCams just needs to be sure there is a market before they start tweaking and working out a new cam for 2.9's.

Sounds like spam

And 2.9s are pointless to put money into. Make one for a 4.0 and make it cheaper than Summit.

Shot down!!! Ohhhhhhh!

Yea the 2.9 isn't really worth putting money into.... But if a 4.0 swap just isn't in the cards for your truck then maybe a little won't hurt.

It would be nice to have that option.

They've been making cams for the 2.9L for a long time. The cams they make are not that expensive considering what they're making it for, and it's best to work with them on the cam profile anyway. If you're going to make a custom cam, might as well have it made with your set up in mind. One cam does not fit everyone.

IMO the market for an engine discontinued in '92 plagued with head cracking problems and oiling issues is not going to have a worth while market in 2012 for a "one-fits-all" camshaft. Camcraft offers RV cams that a computer friendly, they don't even advertise them anymore on their web site, but I always still refer people to them. And colt. Not a lot of aftermarket and it's an "arm and a leg" for parts. Anymore it is better (and usually cheaper) to just upgrade to something that is newer, more displacement, and a lot bigger (and cheaper) aftermarket.

This is not spam. Probably came to the conclusion from a lack of spelling and grammatical errors. I just think that a lot of people don't have the money for a swap, and upgrading the 2.9l is an only option. I just think it would be pretty cool to have another cam option out there for a slight performance upgrade. Don't put the idea down if you don't support it. I was asked by the owner to get an opinion. That's it. Thank you

Another 2.9L Cam Option

Not to be mistaken as a shill for a cam grinder, but I just got a cam from Steve Long Racing (SLR) Cams in Calif. for my yet-to-come-together 2.9L carb'd engine. I doubt it is computer-friendly; this engine has 3 carbs and a distributor (for now) and 1.6:1 roller rocker arms. Yes, it's a one-off oddball for an old oddball car. But I suspect - I don't know for sure - that SLR can grind a cam that will work for someone who chooses to play with the 2.9L engine.

Roller rockers?

I know this a few months old, but since somebody brought it up.

What do you mean dont put the idea down?!?! You wanted opinions, you got one! So its either, say you'll buy the cam or dont say anything?!?!?

Roller Rockers for 2.9L (was Cam Options)

I've been experimenting with roller rockers made for the 2.6L and 2.8L Ford "Cologne" V6s on a new World Products 2.9L head, though it could be done with any 2.9L head.

I've milled the sides of the stock cast aluminum rocker shaft pedestals to allow the rocker arms to line up better over the valve tips. (I've gone this route because the guy who makes the roller rockers pretty much refuses to make arms for the 2.9L engine because of the increased offset and poor arm-to-valve orientation on the 2.9L. Seeing how bad the alignment is, I can't blame the guy.)

I've replaced the hex head bolts with allen head cap screws to allow the pedestals to be milled enough for the arms to line up over the valves. I'll either have a portion of the allen head cap screws' shanks milled to allow for proper oil routing, or I will further mod the pedestals with an oil distribution groove or two. A small o.d. AN-grade flat washer will be fitted to reduce galling of the pedestal top.

The real test of whether this works will be to see if milling the stock cast pedestals weakens them to the point of failure. I'll build the first engine as a street-going guinea pig. If the milled stock pedestal idea is worthy of just the trash can, I'll have pedestals milled from billet aluminum. My few fellow conspirators in this madness are suggesting that steel pedestals would remove all doubt about integrity, but we'll see if we have to go there.

The accompanying photo might better explain what I am doing. The front assembly has not-ready-for-prime-time pedestals made from billet aluminum. The rear assembly has stock cast Ford pedestals with lots of milling done to the sides. Once I have the pedestals milled so the arms are where I want them I'll have aluminum spacers made to keep the arms in place.

To the OP; I would say this would be a niche market. I would be interested because of class rules.

That's pretty cool! No idea they made roller rockers for the 2.6 & 2.8L engines.

 

[dave2575]

There freaking awesome! I'd love to see them when your done.

my yet-to-come-together 2.9L carb'd engine.

Are you using the intake from Burton? Just for fun I ordered a catalog from them (took like 2 months to get over here to Alberta) and they have got some dang nice parts for the colognes!
