Retarding the cam reduces cranking compression, reduces bottom end performance and can increase top end performance. On mod motors usually the cams are ground in a way that fits before ground for performance (we speaking about cams for stock type motors). Mod motors really like the ICL down around 110 degrees but many cams are machine for much higher in order for them to fit correctly.

Most N/A stage 2 cams have too much overlap to pass the sniffer test easily. Your better off with a stage 1 type cam for that situation. I passed comp xe262ah cams through smog with a custom tune and it honestly passed by a good margin.

There are so many different types and sizes of stage 1 and 2 cams. What one manufacture calls a stage 1 might be almost the same duration and overlap specs as anothers stage 2. You need to learn more about cams to trully understand what is happening as opposed to just stages....

Its generally though that stage 1 cams will have more bottom end hp but less top and than a stage 2 cam but much of this depends on the actual cam, installed ICL and tune. I will say I LOVED my xe262ah cams. They picked up hp everywhere and about 25rwhp peak. They werent super radical but they did have a nice pick up in power with a stock type powerband and shift points.

Did you have to degree your cms cams?

[chiefsmustang20]

I have the cms stage 2 and i just tore my car apart last week and only had 1 piston that slapped a valve but that's because It was burned and got hung up .... Degreeing a cam is just to see if it's straight up to spec I've done my cams and the comp cams and have had no problems with ptv numerous times ...

And I never mark my chain before I take it off

Based on what you've ordered them like that? power gain? easy-ness?

Im looking for bolt-on cam's as well, been searching for quite sometime but I read different things at every different forum

Now I understood the following:

- The PTV issues can be bypassed by a good timing,
- Stage II HiTech's are bolt-on's (No need for new pistons and springs and retainers and stuff) and will throw you close to the 300rwhp range
- Comp Cam 270's are also bolt-on's but 278 aren't
- Cam's with rough Idling will usually lose torque but gain HP (race cam's i guess)
- CMS stage 2's are mostly recommended by everyone but I don't know their gains... I feel they're less than HiTech's (from what I've seen till now)
- Usually with Stage 3's or 4's you need heads/ported heads and piston/timing works (not so Bolt-on)
- Some people re-grind Stage 1's for more gain but I have no idea how hard/worthy is that
- Im looking for a bolt-on Cams which will boost my power band everywhere equally, torque is important as this 4.6 isn't a dragster 12,000 rpm screamer! so I guess CMS stage 2's or HiTech Stage's are recommended (still needs to search)

I wouldnt knock the xe262ah cams that much. They may not make as much peak HP as the CMS cams but they do make a very nice broad HP improvement. If your not sure which was your build may go in the future then those are your cams. They're ground on a wide enough lob sep, more exhaust duration for better cylinder blow down that they will work well N/A, on the bottle or with a blower. I ran a 125kit and picked up 155rwhp when using those cams.

[BaznastyDave]

Not knocking them, there are a bunch of cams for the 2V and these are the only 3 i would put in one N/A. CMS has the best gains all around, the Hitech's usually have more PEAK HP but less WTQ and not as good across the board as the CMS, the Comp cams are good all around but just not as high of gains as the CMS. I would not get a cam based off of what they make PEAK HP wise.

Looks loke im going with cms stage 2 at this point. What rpm's can you take them to?


Also if i get trickflow heads can i run stage 3 and 4 cams?

I shift at 6,700rpms at the track, iv held it on the rev limiter bouncing around 7K more than once and it runs fine.

LOL wow. Built ford tuff. But when it breaks we'll say found on road dead. From a hero to a zero just like that lol.

F8TL shifts his @ about the same

Your somewhat right. For your goals i really recommend a stage 1 type cam. Alot of cams lose no bottom end but they surely dont gain. Look into MHS stage 1 cams also. Nick really knows his stuff.

I wouldnt run anything from Hitech. Garbage in my opinion. Hitech is the worst about claiming their cams fit perfect, no degree needed, no springs, more like no common sense and no motor for the buyer after the valve smacks a piston. All cams should be degreed.

Do a google search for all the cams you listed and all the types you find out about. Search terms like MHS cams dyno, "" cams dyno, "" cams review, install, hp gain...... google everything. You will probably figure out exactly what YOU want. Everyone here including myself is going to tell you to buy what THEY like.

yeah kind of a dumb claim...although the cams should be degreed anyway.

as for the cams, they make a good product and they don't need valve springs. been running mine for 2 years now with factory springs.
