pro55 cam cores
What exactly is a pro55 cam core do they nitride the surface to make it harder. Just by looking at it if I bought one how can you tell its pro55 a different surface look ? lettering on the front ?

Besides the chilled iron lifters what about the hardenable iron lifters they talk about. They entire lifter seems to be made out of better material.

I'm going to have to do some compromising. What if I wanted a high rpm band but not really enough compression running on pump gas. Wanted a cam that is not as high rate but not as slow as 40yrs ago. Lots of lift and a fairly tight clearance. Using a pro55 cam core for more insurance and some less spring pressure then say the 420lb springs crower recommends for there oval track 220 series cam. Another words the cam/lifters would have to last. I would be willing to spend more money for a lighter intake valve maybe something like a hollow stem stainless. The cam would cost me some power but maybe I can come up with real good heads.

Thanks very much for the info, I've never had the chance or need to use the (new to me) solids with the EDM oiling hole - but I like the idea.

Checking more into it the hardenable lifters will work but the chilled bottom lifters are better no difference in price.
now i'm going to find a PAC brand behive spring will do the job with a little less pressure.

I would not recommend a beehive unless you are going to spintron test the cam profile. OEM's spend millions tuning engine parts to live with other engine parts. The Beehive is a wonderful part if you have an extra Million in your back pocket to build a spring that is tuned for a given cams frequency in your operation range. If not go old school and be happy.

The cam companies selling many different versions of behives have not tested them to see how well they work on many of there cams.
Comp cams who many on this forum think is gods gift to cams list them as an upgrade to there most extreme flat tappit cams. You telling me this godbold or whatever his name is the big guru at comp cams just threw some behive springs up in the air and says I think they might work then list them for sale no testing.
I suspect comp cams has a spintron to test things knows for sure whats going on along with other cam companies.
I would not have a hydraulic anything if you gave it to me for free. Its either a solid roller or soild flat tappit. On a soild roller it would be a twin spring for sure no doubt, on even a radical solid flat tappit the behive will do it easly.
Chris i'm taking care of old school for sure an antique two valve pushrod engine even the older version with no computer management and a flat tappit cam.
