I have just completed a total rebuild on my TC engine during which the camshaft was replace with a standard 'Crane' cam from Moss Motors. Does anyone have any information regarding recommended rocker clearances using this cam? Currently they are set at 15 thou. Maurice TC9357 [Non-text portions of this message have been removed]

Hi Maurice, when you say `standard`, do you mean Crane`s replacement for an original profile and lift? in which case should`nt they should be set at 19 thou....on a hot motor....

Maybe or maybe not. Although the amount of lift is the same the actual profile of the crane cam is quite different. The cam lobes are considerably wider (reduced wear) and the base circle much larger in radius. One's first reaction when receiving the crane cam is that you have been sent the wrong one but it does in fact fit. When used in the TD the rocker clearances for the XPAG were reduced to 12 thou.

Maurice, Crane Cams has a website that has access to all specifications for the cams they sell. If you know which cam you received from Moss you can access their site and download the spec sheet. It shows the valve lash and degrees of lift. (There should have been one of these sheets in the box with the cam when you bought it from Moss.) Just do a Google search for Crane Cams and you will find their website.

I think you and your engine will be a lot happier if you adjust the valves on a cold engine. Even a warm engine will give you false (i.e. too tight) readings. At least, that's what I've been told and follow on my car. _Peter

Peter, Your engine will be a lot happier if you adjust the valves on a hot engine, the reason being that you are operating your engine at the elevated temperature and everything is now stabilized, everything in the engine expands & contracts at a different rate, and it is at this time that clearance should be to specification. Nuff said. Gene Roth

I use this Cam, and I just set both to 19 thou hot. BTW, I did not need new pushrods, perhaps because my rockers have been refaced at the valve stem end. I wonder if using new rockers would necessitate the shorter pushrods. If so, can pushrods be shortened by a competent machine shop. It seems the ends are just pushed in to the tubular rods, then the rods are hammered to hold the ends in place. -rick Rothgene Roth rothgene@msn.com> wrote: Hi
