Looking for feedback on Erson Cams. I'm hoping to get some insight into your experiences with the quality, precision, time it takes to receive a cam from Erson, and contacting sales and technical assistance. Good, bad, or indifferent.

They still make cams? They make them for something other than a small block Chevy ?

Do they still have the old grinds as well? The Super High Flow II was a great hydraulic for a stock inch Street Hemi.

Friend got a Erson High Flow from Summit for his wedge - close to 300 duration and 475-480 lift

I don't know if it has the same specs as the old days or if it's a modern grind

Seems like alot of duration compared to lift myself - but he seems to like it

There's a lot of discussion (here and other forums) about the poor quality of aftermarket cams/lifters on the shelves today. I don't run an Erson (or any other aftermarket) cam, but when I read your post, the first question that popped into my head was: I wonder what, if anything, Erson is doing better than everyone else to prevent this? Also, do you manufacture your own lifters, or do you source them from elsewhere?

Ran your old 306 (# I think?) in a few sideoilers back in the day. Great performing cam! Where is a link to your mopar cams, please?

Hello Russ !!! I know you guys inspect every cam I've seen it during my visits for Radiac Abrasives. Tell Troy and the guys I said hello.

How about posting a sample catalog of your Mopar grinds???

I had my machine shop check into one of your grinds a year or so ago. It appeared to be a "modern" grind, by the adv, .050, .200 and lift compared to a comparable Comp "modern" lobe.

I work part time at a shop that uses lots of Ersons--First Class quality--EXCELLENT tech help and turn around time --they are as good as any grinder out there. All the BS about "modern" grinds always chaps me as an engine builder--customers will take months and spend weeks to select the PERFECT latest hi tech Whamodynoe 9000 camshaft--then almost always they could have made a better choice and do some other thing that defies logic and hurts the build way more than the less than perfect cam would--The cold hard truth is that most all "modern" grinds are MAXING out usable lifter area--a luxury Mopar had--as in had at one time but now these grinds beat the heck out of the valve train--have used up the extra lifter diameter "safety zone" that Mopar has always enjoyed--and for WHAT??? A Few extra HP that the Computer "says" will be there??? So what if it is 10 extra HP??? Who cares?? Now you are beating up the valve train--having to use crazy spring pressure to control this stupid computer designed ( and almost always UN-TESTED) junk--killing lifters--Oh Boy!!! I gots me an extra HP--Yahoo!!!!
Erson is great! I know shops that can build more HP with a $52 big Summit cam than a $400 custom because they know what they are doing with the other 95% of the build.
Ok go back to wasting your nights picking that perfect dream cam that will make your engine perfect. I will build another with the ole Scummit special that will melt some more tires and make another customer happy and I will probably send it out the door with way less spring pressure than you would approve of yet it will still turn ( and control) all of the usable RPM the cam can muster.
I guess I should start using Comps newest roller cams that Now require ( per their advice) near 1000 lbs open pressure to control--oh wait ...my lifter wheels just passed into the oil pan! But..that thing made some extra HP because the computer said so

Are your cams chevy profiles on a Mopar stick?

Ok Ok I just came off a 16 hour day and am a little ragged--but Erson is a great cam seller and yes I have made awesome HP in a Mopar with "ole Chevy lobes " on Mopar stick--everyone used to
Yes the latest will net you a few but it is at a Big price IMO

I use Erson cams more than any other. As Russ said, they have many new profiles, as well as the time proven designs. If you speak directly to Erik at Erson, he can help with the best profile for your application.

I will say, the new 3 piece core, billet roller cores are the best. They have a cast distributor gear that is replaceable. It does not require a bronze gear on the distributor either. These cores are made by Callies and the quality is outrageous. I don't know if the availability covers all makes yet, however.

I never wait longer than a few days for a custom grind, right to my door.

At one time Erson did a group buy with www.slantsix.org I never bought one. I wonder about the quality of blanks for the slant. Regrinding a stock cam could be an option. I'll post a link to the group over there.

I'd also like to see the latest catalog and cam profiles for Mopars. Can't find anything on the web.

I run a Erson in a 383 that has been in a Challenger, Dart Swinger & now a 56 Plymouth. 906 heads, Holley SD intake & TQ carb. The engine has, and continues, to perform flawlessly. Great street manners, nice thump at idle & plenty of giddy-up when the traffic light goes green. I'm very happy with what I have.

My reference page is a worn xerox copy of the Mopar section of a 1984 Erson catalog from a Super Shops parts counter.

I ran a Erson 270 grind in a slant 6 for years. I would love to have another, along with a 280! With a 270 cam, 3.55 gear, 833od, mildly ported head with big stainless valves, a super six intake, 2.5" exhaust, and a mopar electronic distributor using a gm hei module, my 84 swb truck would pull a proven 25-27 mpg at 70 mph, if not bucking a wind over 15 mph.
I ran this cam for over 75000 miles with no issues whatsoever. A lot of people thought it had a healthy small block in it. It sounded really sweet! I was never kind to that engine.

Our web designer is working on getting a PDF on our website that will contain all of our Chrysler grinds. If anyone would like us to mail them a catalog that has all the Chrysler A and B cams in it and a list of our masters for our profiles, we'll be glad to send them one. Just PM us requesting it with your personal email address and home address for the catalog. The file is too large to post in this forum. As far as our profiles being Chevy profiles on a Chrysler stick, we have profiles that are meant to be on 840 tappets, 870 tappets and 900 tappets. Every cam company uses multiple lobes for multiple applications. It's just a matter of how aggressive you want your ramp profile to be and how hard you want to beat up your valve train for which profile we put on your cam. If you get our catalog and look through our lobes you can pick out the profiles you want on your Chrysler stick. If anyone has any other questions or anymore feedback, we welcome it. If anyone is ever in our area, I would gladly give you a tour. You can ask Martin from Radiac. I'll gladly show you around and proudly show you the quality and craftsmanship that we grind into every Erson cam.
Thanks
Russ
