268h comp cam

[mdb205]

So I just bought the Comp Cams high energy 268h cam kit for my 65 289. I've been trying to find a video or a recording on the cam, but I can't find anything. Can anyone give me an idea of what the idle sounds like? or post a video maybe? Thanks.

i believe that was the cam i had in my 289. i don't recall any lope if that's what you're looking for.

Their web site has the video of them

They do have sound clips and videos, but they don't have any of the high energy 268h...I've been looking for at least a month now and I can't find anything.

I GUESS I can video it and post it tomorrow. I have the cam and works great with my setup. Are trying to see if it lopes bad or something?

[mdb205]

I would really appreciate that! I just really want to know what it sounds like before we put it all back together and run it. I keep getting different answers from people about this cam. Some say it has a rumble to it and some say it sounds like a stock cam. I want it to be noticeable, but I don't want my neighbors to get annoyed by it.

[sdmustangrider]

It actually sounds like a stock. It's not like a grumble grumble sound. Pretty much it's like a chilled sound. Put sounds great and performance wise when you step on the gas!! Think my neighbors are more annoyed with the exhaust.

[mdb205]

Well that's kind of disappointing...comp cams said it had a mild rough idle. So I was hoping for more of a grumble.

[sdmustangrider]

You can hear it lightly grumble at idle but I've got lots of compliments on the way the car itself sounds. Thus saying, the cam helps out a bit. But I like the performance wise on though. I thought about going to a rougher cam to get the sound, but I guess I'm satisfied right now. I'll throw a vid on her tomorrow.

[mdb205]

Thanks, I just really would like to know what it sounds like before it's too late...My goal was to get away from the stock cam and have a little rumble at the stop light.

[sdmustangrider]

I'll try to get a vid on tomorrow. I haven't had my car running for a couple months due to electrical issues. When it's in gear at idle, you can hear it loping for sure. But parked at idle, it sounds more flat. I'll see what I can do tomorrow.

[mdb205]

ok, it's no big deal if you don't get the video up. Thanks again.

I had the HE 268 in my old '67 fastback (289.) As noted above - it ran great, but if you're looking for a little "chop" at idle, it was barely noticable - even with my stock converter/C4 in-gear. (It was like a stock-"plus" idle.) It did have great low (off-the-line) and mid-range torque.

For my current '67 vert with a 289 transplant - I went with the Comp XE 262. (It has a split pattern - intake is close to the HE 268, and exhaust like the HE 270.) It has noticeable "chop" at idle (C4 - stock converter - 3.00 gear) and as far as I can remember, the throttle-response off-the-line is about as good as the 268, and it pulls nicely through the rpm-range.

I know picking a cam for sound is certainly not the right approach - but to me (IMHO) the XE-262 wins hands-down with the split-profile. I see no negatives (compared to the 268 performance-wise) and I love the sound/chop at idle. (The Comp catalog shows the 268 operating-range of 1500-5500, and the 262 is 1600-5600.)

Good luck!

I too have this cam in a newly built motor that I haven't run yet. I'm looking forward to the video.

Well I made the last minute decision to switch to the "nostalgia" comp cam. The intake duration is the same as the 268H, but the exhaust duration is 226 instead of 218. It also has a little more lift. Does anyone know if it'll work with stock replacement springs? I'll find out soon enough but I just want to see if anyone already knows.
