Yes there are better mods for the money, but there are not many mods for the 4.0 out there so we should take what you can get. I know something about building engines too (check out my webpages), and I do know that the factory by no means optimizes the camshafts in most of their engines, even for the intended application. As an example, on the old 5.0 HO engine the camshaft specs were altered around late 1989-early 1990 to be a little less agressive on the ramps, to alter the duration specs, and have a wider lobe separation and this actually had an adverse effect on power production which along with new SAE testing procedures led to the engines being rated at 205hp instead of 225 (both underratings a littls) and affected the power band of the engine. The 1993 Cobra engine, although it had better heads and intake plus 1.7 rockers not seen on the regular HO, actually had a less agressive camshaft than the regular HO (the extra lift spec came from the 1.7 rockers). The ramps were milder, the lobe sep was wider, and the duration specs were changed. Many engine builders will tell you that putting a pre-1990 HO cam in the Cobra engine can be good for as much as 20hp. These cams were not optimum even for the intended usage. Why were they changed? Well, in the original HO cam there were complaints of valvetrain noise and idle quality (by little old secretaries with pretty V8 Mustangs I would guess), so Ford revised to be less lopey (the old HO did have a little "bump" if you listen for it and the lifters did make a little noise riding over those agressive ramps), with the Cobra I have no idea why they changed it so much.

What I am getting at here is that a properly designed cam that takes into consideration the stock 4.0s airflow characteristics and useage can improve even a stock engine. Will it gain you 50hp? 20hp? Maybe not. Will it improve throttle response, rpm range, broaden the power band? It will definetly if designed properly, and Comp knows their stuff. Will it be cost effective? That is up to the buyer/user, but when had modifying an engine ever been cheap? It is up to you to decide what you want and to make the proper decision as to what kinds of mods you want to make. To each his own I guess.

1 of my next major mods is to do the Comp Cam's 410 cam in my truck.....since it is designed for low end power..........a cam will show a difference even on a dyno....

While I respect your opinion I see two outcomes from this, Either little to no actual increase in output, Maybe as much as a good intake and exhaust system would entail, or a way too agressive cam for the stock hardware. I believe in doing things right or not doing them at all, and $1500+ for a 7% power increase seems like a waste of money and resources. Granted if I had the engine apart for some other reason I can see the point, but I still contend most of the people that will buy this cam will buy it for the soul reason of telling their buddies that "It has a cam in it" Now This is just my opinion, and Yes working on a motor is expensive, but to get there are better cheaper, less risky ways of getting that kind of limited HP and Torque out of these machines, and IMO it is either a waste of money or something stupid that will end up costing thousands more in repairs down the road. Nick did it the right way, He did his homework and invested the money to do it right. Like I said I got no horse in this fight, It ain't my money. If people wanted to drive around with ceramic piles of dog poop on there hood, It's not my problem, but it doesn't make it less silly

Ahh they just caught me on an off week where, I have a friend who wants to cam his Cordoba because, "Then it'd have a cam in it" and he doesn't have two nickels to rub together to do it right. Nothing is wrong with the car and it runs like a champ, and he wants me to help him put a cam in car and no matter what I tell him about what's going to happen with the aggressive cam he bought and stock heads, he won't listen. He Doesn't race and the car is a Lean burn 400, It is pointless. and Yet we have been going around covering the same ground for about a week. He calls me daily to ask my advice and I am going nuts. It's Like argueing with Ranger guys if 35's will fit on a non-lifted ranger. Some people just have to learn the hard way.

Long story Short (Too Late) I am sick of hearing about Engine mods that are pointless.

^^^ LOL...... I could see how that would p*ss you off... I have the same argument with my buddy about mods to his ram. We keep going round and round that a cold air kit will give you "UP TO" 20 horsepower. So by his calculations he has 45 extra hp from cold air and dual exhaust.....

Pissed is the wrong word, Annoyed is more liek it. This all started the day I told him I was buying my car, before that he was perfectly happy with his stock car. Now its an emergency to get it cammed! Not to mention mine was done right and I still have to a Valve train tick problem that has to be solved.

No.... the OHC (like the modulars) don't really lope alot... But I thought that was common knowledge.

Nice lightning though...
