    Not 100% sure, but I believe those are Morel...you'd be surprised at how many hyd rollers are....
    C Srtraub can tell you.
    What do you want to know about Erson stuff? Who makes it, or ? I'm sure they buy their springs and reatiners/locks...maybe from Chris, not sure. Nothing wrong with their cams that I know of.

    No Sir, not asking about the Erson stuff for myself but a friend with a SBC.
    I however was curious about the Morrel hyd rollers being the same "exact" piece that's in a PBM box.
    I'm aware some things are a name game but also a generic part might not have the same quality as a name brand >and that's where a buyer must beware.

    Default Hyd lifters

    Regardless of flat or roller type, the hydraulic lifter is the most precision piece in an engine. The internal numbers are in the .0001/.00025 range to make them work. Seems like forever Rhodes made most of the lifters used in US engines, and the aftermarket people re boxed them, and jacked the price up. I would imagine it is the same today, just a different machine shop doing the precision manufacturing......... I know the hyd rollers, (factory replacement), are even more than the pressure oiled solids!!!........Ray

    PS I seem to recall when Sig broke away from Isky there was a period of marginal camshafts and a lot of break in failures. That was 100 years ago, or so it seems. Haven't heard anything about Erson lately......Pro or Con...........Ray

    As far as I know and have been told, PBM's are Morrel's reboxed.

    Erson's raw billets are supplied by Crane, then ground by Erson in Carson City. Most of mine are customs, but I also use some of their mech and hydraulic flat tappet types in milder builds(JB 200 & 300, Hi Flow 2H and 2M). I have no problems with them running flat.

    Erson's FSP Springs are Manley Nextec's reboxed. Ditto on the TI retainers and 10 degree locks as far as I know. I have no problems with any of their stuff at the 850 hp/7,000 rpm level, and have used it for a long time.

    Hope that helps.

    Is Steve Tanzi still at Erson? If so he is a great guy and has tons of experience. I used several of their cams over the years and I was happy with their performance. Steve used to get pretty aggressive with his specs if during the needs assessment discussion there is any incling of making max power with a lack of regard to driveability so be real in that portion of the conversation.

    Steve was the manager up there when Erson was with Mr. Gasket. Now that their PBM, I don't know. All my orders go in thru the website except for the custom rollers now. For those, I normally speak to Tom.

    In the days before oem rollers, Johnson made more lifters in one afternoon than Rhoades did in a year!

    PBM does buy from Morel, but there are now 3 series of hyd rollers, the street series, around$300 a set, the std series $579 a set, and the Ultra series which is $649 a set.

    The Erson stuff is good stuff. Tanzi was still with the company as of PRI show.

    Yeah, and all they were was "bad" lifters.

    Default S & S Harley Performance

    When I worked at Jim's Machining in Camarillo we made most of the internal stuff for S&S. I've had many people tell me about how much better S&S stuff was over Jim's........Sure, we made their stuff better, sure.........Roller lifters, (tappets), Pinion shafts, crank pins, flywheels, rods etc. We also made the Screamin' Eagle line for Harley when it was just getting started. All these components were the same pieces Jim sold for years, just re boxed/engraved with logos etc etc.......Kinda like antifreeze, 5 or 10 brands using the same basic ethylene-glycol with different colors in it..............
