Performance cam? is it worth it?

I am doing a complete engine rebuild on a truck i picked up for really cheap. Here are a few detail on why and has pictures.
Can a bad FICM cause engine damage?

I have decided to shoot for 450hp to 500hp range for this build which from what I have read is not very hard. Basically 155 30% injectors, mild turbo, good tune and exhaust will get you in the ball park. My question is... would it be worth the money to buy a mild cam? Nothing that would require fly cut pistons or anything. Would be interested to hear from people who are running one and how much difference it made. Also open to suggestions on this build. Things people wish they had done or are glad they did when they have the engine tore down.

P.S. This is an Automatic dually with 170,000 miles. Bone stock.
Thanks

For what you are wanting, just save your money. $1000 isn't worth the few ponies you'll get. If you were going to use way bigger injectors and turbo(s) I would say go for it. A ported intake manifold would be better money spent, or getting the heads ported and gasket matched.

You don't need the cam. I'm on a stock intake and heads, I put down some decent numbers. Put the money else where.

I have to agree with these guys for the numbers you're wanting, however though, I know me and I'm a tinkerer and if I had a shred of inclination that I was going to go for more than what you're talking about in the future, I would pay the money for an aftermarket cam as opposed to buying a new stock cam (which you should do IMO if you're putting in new lifters, which you should do if you're doing a full blown engine rebuild). Hope this makes sense. Just my opinion.

This one case I'll say 500hp ain't a waste since your motor dropped a deuce. Why not since your doing all that, I'd add a regulated return for the fuel system, plus all the engine updates, then let her eat.

Anyway, Nate is right, if some money gets freed up and you'd like to get that badonkadonk sliding around real easy down the road, a stage 1 colt will give some more air, plus if you can swing it, check out the Borg Warner s362 fmw with cutting edge diesel up pipes. From the vids cutting edge(06powerstroke06) has up, it works very well. Plus, that charger would be a great little brother to an s475 or s480, you can run some big sticks with either of those.

I said that assuming the "super power bug" bites down the road.

I agree too. The power you're after can be had easily with other parts that aren't as intrusive...you'd have to consider fly cutting the pistons, and honestly if/when I build up ones of these motors for me, I'll probably use an aftermarket cam even though I'll probably stay around 600 HP or so...maybe more, but if I go with a cam also make the jump to solid roller lifters, and adjustable rocker arms, but thats like another 3k worth of stuff. If the motor is apart and you planned to run more than 35-40 psi of boost I'd recommend valve springs, and the shorter 6.4 length pushrods. There's a few threads that talk about the valve train issues these motors had from the factory. The link in my sig talks about it some, but in a nut shell, for whatever reason the motors had way too much hydraulic lifter preload from the factory, and it has caused some problems for lots of folks. As more and more people are getting into ported heads and trying different combos and all people are reaching new HP levels previously thought to be unattainable, but for your estimated power goals I'd spend the money elsewhere, like maybe save for a trans. I haven't heard of too many living above 5-550 for very long.

If your plan was above 600HP the cam should be considered. The overall cost is what kills for all the supporting parts needed when you go to a cam.

If a cam swap had shown decent gains you can bet everyone would be doing it during a stud install.

Well considering all that goes into a cam swap, they pretty much are a waste to do unless you're doing a full on COMPLETE engine rebuild like the OP is doing. I still stand by my recommendation for a cam because IF he wants to do the job right, he's going to need a new stock cam anyways so I know I wouldn't pay $400 for a stock cam when I could pay $600 for an aftermarket one that I could put in and find out for myself if it was worth it. As far as supporting mods go, I would just run a Stage 1 Colt cam with 6.4 push rods and RCD's valve springs and call it a day. There shouldn't be any need for valve reliefs in the pistons with that cam. Again, just my thoughts and I would not do a cam unless I was doing a full rebuild.

Very solid point....

You can get 500+ HP with just a tune, exhaust and intake.

A cam isn't that much...$500-$600 for a colt cam from RCD would be the ticket seeing as the engine will be torn down and rebuilt.
