When did they start putting hyd cams and lifters in 225 /6? I searched here and /6.org and couldn't find a answer.
Yes, no better than a properly adjusted solid. My 67 motor purrs like a kitten sitting on a sewing machine, no valve noise at all. And no vibration either, can balance a pencil on the intake at idleIs it hard to change over to a HYD cam?
'81 was first year for all slants to have hydro lifters. There was a small production test run in '78. You need a hydraulic cam with a grooved rearmost cam journal (or ungrooved rear cam journal but grooved rearmost cam bearing) for oil feed via the head through the rocker shaft and rocker arms down to the top-feed lifters via the hollow pushrods. You also need the rocker shaft, rocker arms, pushrods, and lifters.
Er-ruh why do you want to do this? The solid cam selection is much broader.

2x....
Not to mention more powerful.
That's a good reason. Pick your camshaft carefully; the stock '81+ hydro cam is pathetic. Talk to these people.
I'd keep the solid cam (if yours is still good) even if I had to hire someone to adjust them occasionally. The cost to hire someone to change the cam over to hydrolic would fund valve adjustments for many years.It would make it easier on me physically to be able to maintain the engine properly and the same reason I cannot drive a manual trans car or truck no more. My back and legs won't let me.
is john even still with them (ERSON)??
You caint prove Erson is even still in business to me. Much as I've called and many emails as I've sent with no response.

Sig Erson Cams seems to be a subsidiary of PBM Performance Products. Whether they are still actively developing products or living off of past success is unclear.
Comp will grind you any damn thing you want though.

Not quite...
I wanted a .500-lift, (with stock rockers), 220/228 duration @ .050" flat tappet /6 cam with 114-degree lobe separation, and was told by Comp Cams, "no can do."
They said, "We don't have any blanks to support those numbers (turbo cam.")
So, I did the next best thing; I had them grind me a .484"-lift, 200/220 duration @ .050"-lift, cam with 114-degrees of lobe separation. Now, I'm on the prowl, for a REASONABLY-PRICED set of 1.6:1 rockers to get the lift I wanted.
This all started when I wanted a /6 roller tappet cam... they won't grind that, either, unless you supply them with a $1,000.00 roller "blank." And, maybe not, then...
So, don't think that Camp Cams will grind you "any damned thing you want," because they won't...
crower will make you a whole custom billet one:cheers: when i do my MEGA 6 thats what it will have
Are you saying they will grind a roller? Where do they get the blank, and how much $$$$ are you talking about?
And, what is a "MEGA 6"?????????
from a peice of billet steel you can grind a cane if you like! there is no black its a complete cnc cam... money... lots of it im sure...
a mega 6 is the race motor im building in my head... n/a of course...
