I'm like 90% sure that is the LE3 cam not the LE2.

 

There is a new verison of the LE2 cam, the 234/242 is the old verison. hsyr is right it's closer to a LE3 now.

Anyways on to the 227/233 cam.....

Even though the duration specs of the cam are not in a bad range the lobes are old news and are not the most modern cam lobe designs. They are the 344X series of lobes, (3441S 227 @ .050, 3442S 233 @ .050, and 3443S 239 @ .050) they are old lobe designs that don't have the spin tron testing and modern cam design that the new lobes give you. They are rather aggressive lobes that don't offer very good valve control and too me are more of a gimmic for selling cams than they are for giving you HP and TQ. Just because they use a different duration doesn't mean they are "new and special" actually that's not really the case, they are old and out dated.

Your better off telling Lloyd what you want and asking what cam will work the best with your combination. A LE1 cam might work better for you than a LE2 or LE3. The cams can be mixed around with the head stages, they just progressively get bigger with a higher number. They are paired up with the head stages because they are more aggressive and match the valvetrain packages on the heads very well.

the 234/242 is the LE2 cam. i e-mailed Lloyd last night and he responded today, saying it's the LE2 cam. the LE3 has a little more duration...

 

That and the lift on the LE2 is supposed to be ~.600" lift. There are many people running the 847 and the 306 with nice results on stock castings. Since LE heads are in the near to distant future, I'm leaning more towards running the LE2 cam on stock heads and seeing what sort of numbers I can put up.

Thanks for the above info! Anyone else?

 

Yeah it was the first version of the LE2 cam and it has about .560" lift rather than .600". The new LE2 cam is different than that cam.

you're right. I read his e-mail wrong.

"Doug,

I used to have 234/242 duration on the LE2 cam.

I have the specs on my cams to make a lil more TQ and still have the same HP and RPM capabilities. I ran some cams on some computer program engine simulators and they looked like they would work better and I have been using them for about 4 months now with GREAT results.

The LE1 is pretty small and is made for mild set ups. It is about 225/232 duration.

The LE2 now has about .600 lift and a lil less duration that that.

The LE2 is a lil more duration than that.

I keep the exact specs quiet until the cams are purchased.

Sounds about right to me.

 

I cant find that lobe on Comps site. Is it not the same lobes as the XE series? That is what I always assumed but now that I take a look I dont see them anywhere?

 

Yeah I know. Comp doesn't advertise them anymore since they are a old out of date profile. The newest profiles are the ones in the lobe catalog. I don't think they even have the new lobe catalog on the net.
