the "results" depends on the whole car and motor and drive train combo!!!...
car wt/CR/rear gears ratio/tranny/etc/etc....

all the cam brands make a version of the 268, contact them and give all of your cars details to determine the best duration for your combo and how you use the car....

to me,
it's the definition of the best "all around" performance street/strip cam,,,,,excellent normal driving street manners, lot's of wow when you mash the pedal,,,,relatively low total engine/drive train parts cost to make it work excellent....

here's a link to some comp cam's dyno results for various durations.....
click on each to read the performance details and motor parts build....

I got one in my 406 with Vortec heads. Good performance. Slight lumpy idle even with more cubes. But, it's the third one. The first two lost lobes. My fault, their fault?

I used a 268 in a 9:1 350 several years ago and was pleased with it. As I remember, it was the magnum, not the XE. I just can't see the need to jerk the valve open and slam it shut with the snappy valve action of the XE and prefer longer ramps. The cam has enough tragedy to contend with, without being asked to work harder than necessary in my opinion.

I have to agree with techinspector1. The added wear and stress on the valve train isn't worth the extra few HP they put out. If it was a race engine it would be another story but this cam is pretty mild and there are lots of other cams that would probably last twice as long and make within a few HP.

I have one in my nova and it sounds real nice. Its only a target master motor with a rpm intake and 600 carb. I've had it for 4 years now and its my daily driver. With a stock stall convertoer it would try to pull the through the brakes when it was cold so I installed a 2400 and no more problems

I have one in a 383 SBC with Trick Flow heads, 10 to 1 compression, an Air Gap intake, and 770 Street Avenger, etc. It's a sweet cam in my book. It has lots of low end, more than my tires can handle, and a decent top end. It starts up nicely, is very driveable, and will run in the high 12's. Check out the dyno figures on the Comp Cam web site.
