Comp cam vs. Crane
So I just got my 390 back from the machine shop and they sent me a Comp 268H cam. My buddy who is building the motor for me ran it and the crane 343901 on the desktop dyno and the numbers look pretty similar. He figures the price of the crane will be a fair bit more than the comp that we have. What are your opinions?
Thanks

Jay,
I'm going Comp (not 268H) on my Tunnel Port project. Price is right, it matches exactly what I'm doing, and alot of FE guys are running them (especially the 268H). Ultimately you have to do what you want, but if the performance is roughly the same why change?

Thats exactly what I'm thinking but I wasn't sure. On the desktop for my motor the Crane has more hp but at higher RPM (5000)but the Comp has a bit more torque down low(2000-3000) which is where i will probably be running it
Thanks again

The crane is a dual pattern camshaft. (Are you running headers? Ported heads) The crane lift is more and it has a wider separation angle.
The Crane is 109.00 without lifters and 169.00 with them at Summit.
If you planned your build up based on the Crane, I would stick with it if I were you.
As far as brands I'd say Crane and Comp are equal, they are the 2 biggest names in camshafts.
On a side note, I notice you guys like really mild cams?

Comp cam vs. Crane
I'm running a Crane 272 degree energizer ( .523 lift) in a 68 Monterey with a C-6, and 2.75 rear, and it's got good power from idle to 6000. Idles almost like a stocker, only lopes when cold. Cost's $120 or so including the lifters at Summit. Ought to also work good in a truck.That H-260 will run out of breath at 4-5000 rpms. What's your comp ratio? If it's 9 to1 then go with a Comp Cams 268H, if it's 10.5 to 1 then go with the Crane.

I noticed they like small cams too. Might as well run a stock cam than buy a 260 degree cam.

I would run a Crane cam. The shop where I work has had several problems with Comp stuff. I don't think their quality control is as good, and the grinds they are selling are chevy grinds. By which I mean that the rate of lifter acceleration is not optimized for the Ford's bigger lifter diameter. FWIW, I wouldn't run a Comp Cam if you gave it to me for free. DF

Comp cam vs. Crane
I have to agree with DF on this one. I wouldn't run the comp cam if you gave it to me. I ran 2 comp cams and neither of them worked well for me. I have a good friend that ran 2 of them also. One went flat within about 2000 miles, the other broke in two.

I've wiped lobes on both a Comp and a Crane in the last year. Wasn't their fault, it was the way the cams were prepped by the mechanic ( me) that caused the problem. Comp made theirs good even though they weren't at fault , didn't try to milk Crane when their's wiped.

Well we went with the Comp cam, we ran them both on the desktop dyno and it puts out a flatter and more torque curve than the crane, and it's the one the machine shop spec'd us. I did some checking on crane and comp websites and for torque there isn't really anything that beats it. Anyways I put all the details on my motor in my gallery. Had it back in for 3 days now and it sure seems to pull well
I just need to get some new exhaust and put in pertronix and I should be all set. Oh and some new tires soon

For you guys who are running dyno simulations.....does your program allow you to enter the camshafts rate of rise on the lifters ? ( lifter acceleration ) ? Crane's cams have much faster ramps, which means more real world power, but this is not always apparent on a computer simulation. Most of the dyno programs I have seen don't allow you to enter this variable. The biggest problem I have with them however, is manufacturing sloppyness. I don't know who makes the blanks that Comp uses, but they have had LOTS of trouble with the distributer drive gears being cut incorrectly.After 6 dizzy gears and 2 differant oil pumps, Comp finally admitted that they had 'a few' cams out there that were ground wrong. This is when dealing with an established machine shop of 18 yrs. How many cams were assembled by some guy in his garage that went bad- only to have the company ( COMP ) claim it was the builders fault. My Boss has built 1000s of engines, and knew what was wrong right away, but Comp still fought us anyway. It took months to get them to admit their mistake. DF

I had a long conversation with the tech guy at Comp Cams when I wiped a lobe, we pretty much agreed that the problem was my fault, but he made it good anyway. I don't know why your boss had such a hard time with them ( maybe his attitude on the phone?) but Comp could have told me I was stuck for a new cam & lifters but they sent me a new cam & lifters anyway at their expense. That doesn't sound like they screw people to me. The only reason I went with the Crane the second time around, was price. I had a very limited amount of money to spend on the overhaul. The Crane 272 degree Energizer was $120 from Summit including the lifters.

Comp cam vs. Crane
well personally i would go by word of mouth (what your doing)
for my engine 335 series 400 most of the word pushes to comp cams 265DEH dual pattern
well is better than sock and ALOT of people vouch for it as the best thing going so i will try
do a search on cm here and get a peice of paper and pen giving extra points to the "ran a ??? cam then swapped a ???? cam big improvement" people
hey or you can leave it to your mechanics descresion... lol

You know talking about comp, I have faxed them "cam help" forms on at least 3 occasions and never heard from them. (And bought other cams as a result)
I E-mailed them one earlier today we'll see if they have improved any.
Looks like it is down to an XE274H or a Crane H-278-2 (343801)
