I don't think many machine shops are equipped to regrind camshafts . I think a flat tappet cam needs to be rehardened after regrinding ???

If anybody has had a cam reground I would love to know more details .

Location ? Cost ? Stock lift or more ?

Even if it one of the big boys that does regrinds , it would be nice for us members to know who offers this service , Thanks in Advance - Ken(Ark)

I did a quick search for a local cam regrinding shop . I have sent them an email and would gladly stop by and chat if the door is opened . If I get any info I will post it .

The company claims it is "The Largest and Oldest Camshaft Remanufacturer on the Planet! "
Chrome Plating is a vital part of Hillcrest Camshaft's operations. Original dimensions are restored every day with our 5 in-house chrome plating tanks. We have the ability to plate and machine camshafts up to 14 feet in length. Chrome plating actually adds hardness, resists abrasions and reduces friction, therefore, increasing engine RPMs and horsepower. The chrome plating process means longer life for journals and bearing surfaces.

If you are thinking about getting it reground, DON'T. These engines have no camshaft bearings so any metal they remove will cause increased clearance with the engine block and lower oil pressure.


Truly profound advice :roll:
TOH
Unless you deposited more metal on the lobes before regrinding, and didn't have adjustable lifters, you have a real problem don't you?


I wouldn't call it a "real problem" but you do have to be aware of the issue. Heck even a new cam or new valves pose a problem if you are sticking with those archaic non-adjustable lifters. Since I was replacing everthying none of that was an issue for me.

I never measured the lobes on the regrind I purchased but my assumption was they had been reduced. And even if I had measured them I have no specification to compare against. I did measure the journals and they were stock. FWIW both the journals and the lobes had been nitrided. Not sure how much that may have added dimensionally or how long it remains on the surface once you fire it up. I think it is sacraficial and dissipates rapidly.

TOH

PS> For a production shop churning out lots of regrinds for many different engines I would imagine build-up with a metal spray would be child's play.

RC Automotive/Chambers Cams which is in Alexandria, VA. reground the camshaft and line bored the block for camshaft bearings in my TR4 many years ago and I would expect they still provide that service. AFAIK as long as the camshaft has the meat for it Roy Chambers will grind anything you want in the way of lift and timing. He does a lot of performance work for the Roger Ramjet racer types in this area :shock: Google turned up many other shops around teh country.
