Is anyone using this roller cam? I havent heard or seen much about it. Do you think it would be good for a 496 street/strip motor?
Here are the specs.

Adver. dur. 335i 329e @ .050 236i 245e

Lift @cam .368i .346e @valve .625i .639e

112 lsa 109 icl

I'm thinking about trying the rpm package w/ the oval port alum. heads and air gap intake.any thoughts?
Thanks , Mitch.

I'm not a fan of Edelbrocks cams. I think you can do a lot better. Look at the advertised duration of 335/229 (this is huge and will want a lot of compression) and compare it to the .050" duration (236/245). A cam with this .050 usually has an adv in the 290º, or so range. And this is a roller?? One of the big advantages of a roller is rapidly opening the valve. This cam is very, very lazy.

Pat,
I copied the specs directly from edel. web site , I hope I got them correct. When you say "lazy" , what do you mean and how can you tell by just looking at the specs (please educate me :confused: )? Not a good cam for street use?
By no means am I a cam expert but , Ive always thought you look at duration @.050 to see the true size of a cam.
Thanks,Mitch

good for street,easy on the valve train, but I'd go with a comp roller or Lunati for power.

Not too many people pay attention to the adv dur anymore but it is still important. The .050" dur is nice for comparing cams since it uses a "standard" for this comparison but .050" numbers mean nothing to the engine. The engine only knows when the valve is open or closed. Just about any calculation requires using the adv dur (seat to seat timing). The RPM cam has very gentle lift rates. You can subtract the .050 from the adv to get the "intensity" of the cam. The lower this value, the more aggressive the lobe. Gentle lobes are easy on the valvetrain but make less power. BTW, this cam has 108º of overlap. It won't make much, if any, vacuum. Look here (http://members.uia.net/pkelley2/Overlap.html) for info on overlap.

This is a very old style cam with very long seat times and very mild lift rates. It will work but there are much better cams.

He, He!!

Pat,

He will get tired of it before it wears out!!

Go with Pat on this, he`s correct. You can get a much better cam than this from various other manufacturers that would still be very easy on you valve train and make much more power. ;)

I've emailed e-brock twice asking about the cam but, no response , I think I know why :rolleyes: . Thank you for the info. Pat graemlins/thumbsup.gif , I just put your home page on my favorites , lots of good info.

thought that seemed weird too, my crower solid roller has 252/254 and only 578/585 lift....
