Cammed 06 GT with 100k mikes??
Would it be safe to cam my 06 GT with 100k miles? I just bought long tube headers, and CAI and new plugs and coils, and new clutch. If its safe is there anything else I would need to be safe?

I'm sure you'd be fine. I have cams and my car has 74k on it. Maybe new valve springs and a timing chain kit since that's gonna be all apart anyway. Best bet would be to call a guy that tunes a lot of mustangs I'd think.

Agreed on the timing chain and tensioners. Check the VCT. I'd replace the oil pump too.

If he's properly or over maintained his engine I'd think he'd be good on the oil pump and rings no? The valve train may need some work but I'd doubt it, depending on how he drives the car. I can't say I've ever heard of an oil pump quitting on a 4.6, not to say it hasn't happened. Normally when I've seen blown up modular motors it's from over heating or neglect. Specifically no oil and no coolant. I've seen a 4.6 2v launch a rod through a block before but that was from a lightening strike that cooked a PCM, left an injector wide open, and caused a big boom lol. And the motor STILL ran! For months! The hole was just far enough up so it didn't leak any fluids, just ran like it had a bad coil! Crazy! Anyway.... lol. Get it checked out but I wouldn't go crazy. The cams, associate parts, and labor are gonna cost enough lol

At 100k, if I'm going to beef up a motor, I'd just as soon spend a little extra for a "soft rebuild" - chains/tensioners, oil pump, water pump - all the little things that are nevertheless vital, but short of a full rebuild of crank bearings, rings, etc. But that's me.
Also, I did a valve job on a DOHC back in the day and that put more pressure on the weakening 100k rings (didn't do a comp check first) causing a lot of oil usage. So I did all that work and money on an engine that should have been completely rebuilt while I had it half torn down.

Wow no kidding. That's definitely news to me lol. I had no clue. Listen to cydnaco! Once my motor ****s the bed I'm either gonna stroke it or get a 5.4 4v. Or who knows. My plan is to make it a NA street/strip car after its all paid for. Well see what happens. Glad you put that info on me though, good looking out.

Yea I just finished skimming through it. I have NEVER heard of anything like that before. Wicked surprising. That's really weird. But hey it is what it is. Just gotta roll with the punches. Maybe it has to do with poor maintenance? I change my oil like every 5 k with a k&n filter with full synthetic mobile 1. Just gotta take care of her and hope for the best I suppose.
That fnsweet link really opened my eyes with comments about Roush.
A few weeks back I was looking at a used 08 F150 with a 5.4L 3V on a lot. Did some searches and found a number of links about its VCT having problems.

It looks like the thrust washer wore out.
