Indiana Posted April 12, 2011 Report Share Posted April 12, 2011 Just sounds like a random aftermarket cam to me. Those painted on and cast in characters have no meaning except to the one that cast them then someone else ground them and painted on some more characters. Whether its mechanical or hydraulic you'd have to measure the lobe height. Reground cams have different numbers engraved into the END of the cam. These weren't on the end were they? Here's the stock specs:http://www.b2600turbo.com/stock_camshaft_id.htm Link to comment Share on other sites More sharing options...

Any help is appreciated That is a camshaft made by EPC. It is a mechanical stock replacement camshaft. Can you double check the A30 casting? It is most likely an A20 which has an .020 oversize journals. They made a A20, and A40, but not a A30. A30 would be .030 oversize journals.

Whiplash Posted April 12, 2011 Report Share Posted April 12, 2011 (edited) BTW a stock cam journal should be 1.3386 +/- .0007. With .002 - .0035 oil clearance. Edited April 12, 2011 by Whiplash Link to comment Share on other sites More sharing options...

Indiana Posted April 13, 2011 Report Share Posted April 13, 2011 You bought a head with a cam that has OS journals and its "rebuilt"? Link to comment Share on other sites More sharing options...
lionbull Posted July 5, 2011 Report Share Posted July 5, 2011 Just found out I have the exact same cam in my car. I believe it needs to be replaced. It is quite jagged on the edges of #3 and #4. Was this cam any good? I have no Idea who EPC is. The cam was installed used years ago. Any suggestions on a proper performance replacement? Thanks Link to comment Share on other sites More sharing options...
Indiana Posted July 5, 2011 Report Share Posted July 5, 2011 Is it oversized journals? That cam was sold under different names, Federal Mogul, Clevite and it could have been a core for a regrind too. I've sent TimC some cores for cams and some were good used cams and some were new ones. Any markings on either end? Could just be a stock replacement.

ThanksDo the lobes look like these?http://www.starquestclub.com/forum/index.php?showtopic=119861&st=0&p=1164483&fromsearch=1entry1164483 Can you mic the journals, base circle and lobe height? We can get a pretty good ideal if it is stock or not from that info. Link to comment Share on other sites More sharing options...
