Yeah after about 3500 it will pull like crazy. You lose a lot of low end, but that's where the blower comes in

For the 278? Hm. I've heard 3000ish. It all depends on set ups and stuff.

Ya like I said summit has the kit with everything including the float tool, u just hook it up to a air compressor to float the valves so they don't drop bro, and the cam retention tool is to loosen the gears and chain so you don't have to pull the chains or cover off... Go to YouTube and look up the vid. It helped me to understand how they easily changed the cams without even taking the timing cover off or anything, just simply made it look supper easy...

Re: Cams

not to just jump into this randomly, but reading above you guys were talking about how stage 1s are better than stage 2s because the stage 2s are rated for up to 7k rpms right? I am running stage 2s and after my tune im redlining at 6700rpms. am I missing something here or are you telling me that it wasnt worth it? or what?

I am still running stock TB/Plenum, and Stock headers. (i know i know longtubes and a 70mm)

Does your car feel more powerful with the cams? If so I don't think it was worth it. Do you have a video of your car idling?

You guys need to go to comp cams actual site because they have the info. On the stage 2 (270) the power band is until 5700, not freaking 7 grand lol. Go to comps website if you want any info. It helped me alot. Also give them a call when you order they will hook you up with the perfect cam for your car/build.

Do I need new springs and valves and cam gears I think they are called as well?
I have 4.10s and still get 20 mpg just depends on how you drive

Max power is made at 5700. But the power band on a stage 2 cam will go WAY higher than stock cams. The can rev and make power till 7000.

Your fine man. The stock intake manifold won't flow enough to exceed that and the internals aren't made well enough to rev any higher either

Not to mention the lack of power up to that 3k range with the stage 2.

The stage 1's powerband can be felt as low as ~500 rpms and up to 5400-5500 rpms, which is more suited for a stock block 2v.

I'm guessing most guys that say they wished they went with the stage 2 either wanted them for the sound or ended up doing some more serious building shortly after and wished they would've waited and done stag 2's.

It's up to you, but after talking to numerous 2v guys it seems that stage 1's are better suited for 90% of 2v owners that don't go beyond the bolt on phase.
Is it possible to get your car to rev higher

It says up to 7500 rpm is that how much it can handle or how much it'll let you do?

Yes it's possible to get your engine to Rev higher.. but you have to remember that a lot of the parts in your engine aren't designed to Rev higher. That's probably it's top power/torque curve at that RPM.

If I put stage 2 cams in could I take them out when I get new heads?

You could.. but this means that you would be buying an entirely new set of cams with your new heads right? Do you already have the stage 2 cams? If so, I would try to find out if you could use them on your new heads. If not.. I would wait to buy cams until you got your new heads..

I suppose if the head design was set up the exact same way with cam profiles from the original head, then you could.. but that kind of defeats the purpose of a new head. If you're going to run the stock cams on a new head, why don't you just port out your stock heads and save the money? Typically, new heads come into play when you want more airflow than your stock heads can give you even after being ported, and your stock cam profile isn't allowing the valve to either open far enough, or be open long enough to allow enough air in. If it were me.. I'd try to get a port job and maybe new cams, or get a kit that comes with heads and matching cams.. otherwise, there just isn't much point in my opinion.

When you say new heads are you talking about port and polished pi heads or something like trick flows?

Re: Cams

I just got the stage 2 comp cams from am just waiting on the install. You need to buy the cam gears the factory cam gears are pressed on and the comp cams require a bolt on gear.

I heard stock gears would work but I guess not
