I have a 68 camaro with the original 327. I would like to get a comp magnum hydraulic cam but ant shure on what size to get. I dont want to get a different converter so i was just wondering what some segestions would be.

I ran a 270H, it worked pretty good. Fairly smooth idle, 15" of vacuum, killer midrange and strong to a lil over 6k.

Next step up is the 280h. That one, everyone will know there's a "hot stick" in it.
If I did a 280 in a 327, I'd make it a solid, it will carry to 7k plus easy.

Would i need a diff. converter with the 280h and do u have any idea about the power gains

If you have the double hump heads, they won't like a cam over a 268 or a Voodoo 60103. I have a 270 cam with those heads and the engine doesn't like it.

With the 280H, they do suggest a converter change. You may be better off with the 268H.

I dont know what kinda of heads it has i think they are just the stock heads

Im getting to where Im not sure if this question can be answered or not but here goes,
stock heads? eeewww....you need smaller than a 268 in magnum. If I was you, get a 4x4 cam and take advantage of the low lift long duration...might even be ok for 1.6's on the intake.
split pattern cam may be more up your alley tho too....good luck.

Dude I wouldn't go with a 280H I just installed a 286H which I know is bigger, but as of now it dosent run too well, i have about 10.5:1 and a 4 speed.
The 268 would be a good choice so would the 270...

I would like for it to sound like it had a hot cam in it though would the 270 give me a good sound and still run good

You need to tell us what heads are on that engine. A bigger cam isn't going to help you if your heads won't support it. Take a valve cover off and write down the part # of the heads. The number will be down on the casting, below the rocker arms. It should be about 7 digits.

The 270 will give you a noticable idle for sure but not to lopey and depending on your carburation...should give you good power. IMO

If all you really want is the sound than go with a comp cams thumpr, eventhough they are not good performance cams.
Duration and lobe sep is going to get you the noise but with small cubes large duration and low lobe sep (under 108*) can kill your motor, as in running like a wounded dog...
you don't want that, no one does.

I had the 268H in the 355 in my other 69 with small valve 481 double hump heads and it was pretty impressive with a TH350 w/shift kit, 2800 stall converter, 3.55 gears, and 285/40/17 tires. I never got a chance to run it on a strip, but it felt like easy mid-13's. It had a noticeable idle, and pulled well through 6000 RPM.

But if you put that into a smaller motor it will move the RPM range higher killing more bottom end. Not what you want on a street car.

My advise is (as always) call a cam manufacturer and ask them. Tell them what you want your motor to do and head their advise. Think about how many combo's they (collectively) have tried and use that to your advantage. It saves alot of frustration in the long run.


Chris:cool:

I might just do that lol

Ive looked around and i think i have either decided to get a 268h high energy, or extreme energy. Can anyone tell me the difference????

.... Can anyone tell me the difference????

In what kind of engine? Small difference in a stock head 327.
Big difference 327 with dbl humps of firepack heads.

I like a 280H in a small block. Ran it in a 350 with 4 speed and gears worked good. Still ran good with 3.08's. Building a 327 this time with forged flattops, steel crank, eagle rods, 492 casting double hump heads with 2.02's, , headers, 650 DP MS. Running a 4speed again and probably 3.73's. 280H would run 6500 in 350 pretty nicely, should be easy in a 327. If it's too much, run more gears or stall or 4 speed. Let's face it .480 lift is not too much.

......... Can anyone tell me the difference????

On the Comp website:http://www.compcams.com/technical/Catalogs/106-07/8-9.pdf

Two totally different applications it seems.

Thank u all for all the help i reallly need to find out what kind of heads i have how can i tell???? is their a code

under the valve cover is some numerical digits. place them here....

O, ill look when its on my mind im pretty shure its just stock heads though

Stock heads cover alot of area from smog choked two barrel heads to 375 HP "fuelie" heads that's why they want the numbers.:)

Yes, if they are 1.72 valves, I am not sure how much good a cam will do. If its 1.94's or 2.02's then it will make a big difference.
