Need cam help

Looking at doing intakes/cam here soon. I'm wanting opinions/suggestions on what durations to look at and who is the best to talk to. I want you to know there is a cam in there at idle, but not to the point I'm hurting performance. Basically, the best idle with the best performance.
For background, I have CAI/Exhaust/EGR delete, extent of performance right now. Gonna be running 4.10's with this as well as an offroad x and 94-98 manifolds.
So basically, what specs would you recommend running for this setup? It's going to be this way for a while and I'd like to at least be able to do heads without changing cams, I'll be ready to change specs later on, just want this to be the best I can for my current setup.

Re: Need cam help

Would something like a 214/214 duration, .48/.48 lift, 110 lobe be too much? lol

Your not a big speller either.

A cam is the heart of the engine, you have it designed around the other things done to the car.

Re: Need cam help

the cam turns and moves the push rods up and down. the push rods push up on the rocker arms which open/close the valves that let air in/out of the cylinders.

Re: Need cam help

110 LSA sounds like quite a bit... I don't know about the 3.8, but with a 5.0 you can't expect a motor with a 110 LSA to really have much of an idle.

I'd look for something along the lines of a 112 or 114. For reference, I'm running a 114 LSA, .512"/.512" lift, 218*/224* duration cam in my car.

You also may really want to look into a cam that is split duration. Ford motors are notorious for having "less than healthy" exhaust ports, and therefore benefit from a little more duration on the exhaust side.

The lift sounds about right though.

Re: Need cam help

Well how much would it hurt to do say heads and cam and leave the intakes for later. I know the car will be kinda starving up top with the stock intakes, but it will only be for a year tops. Just kinda seems pointless to rip the same part of the engine down twice.

That would be ok.

Re: Need cam help

What would you recommend kirk? I can either do gears/intakes/cam now or do cam/heads for now. Which would you do first?

Re: Need cam help

The more I look at the powerpacks from supersix the more I like the stage 2+. I wouldn't be able to do gears for a while...maybe the 7.5 would hold up to that. Still kinda wanting recommendations on what I should be looking for cam-wise. Where's brother corey when ya need him, I liked the idle his car has.

Re: Need cam help

I agree with Brent.

The 7.5 will be ok, I am still running one.

Re: Need cam help

Yea I think the 7.5 will be fine they are alot stronger than people give them credit for. I had a 7.5 with 3.73's in my supercharged 82 5.0 and ran 28-10.5 mickeys with lots of track time and never had a problem however I wouldnt recomend it. as for as the cam I dont know if you are a 5-speed or auto taht cam would never work in an auto the 110lobe sep would bleed off to much compression at low rpm you def need something more along the lines of what b-bunt was saying about 114

Re: Need cam help

Tom from supersix has recommended a 218/224 112 lobe, how's that sound to ya'll? I'm still trying to learn all these cam terms.

Re: Need cam help

I have a 216/216 112 lobe. A vid of my exhaust is in my gallery. It does have a lot of lope but pulls real hard above 3g's.

Long term goals should be kept in mind here. The split duaration will give you a slightly loby idle and it geared more for supercharged engines. BUT, on the plus side a split duration all around is a great cam for N/A and SC'd. I have the 224/230 cam in my car and it's great. And also if you have too allow too much air into the engine but can't get out the air as fast you're going to lose power. EX. I stroked my engine to the 4.2 in 2003 and I went from 180rwhp to 168rwhp. Reason being my exhaust wasn't modified yet enough to handle the 4.2 and was slightly clogged and now i'm at 218rwhp since i fixed my exhaust. Now my other problem I need a new intake manifold that will allow more air into the engine to get me up to about 240rwhp or possibly more. ::sigh::

Well I talked to Tom up at supersix and he recommended that one since I'm looking at possibly stroking in the future and supercharging. With these future mods in mind that is a fairly rounded cam. As far as moving the air out, I have an offroad X sitting in the kitchen and a set of 94-98 manifolds and my mufflers are pretty straight through, if nothing else it'll be flowing too much. I'm definitely trying to build for the future.
