Re: [Amc-list] 195.6 OHV Oil Return Line - just use a pre-cut brake line?

Bruce,

Here's what the crane cams website says about solid lifter adjustment and compensating for a cold engine;

Quote
When installing a new cam, the engine will be cold but the lash specifications are for a hot engine. What are you to do? There is a correction factor that can be used to get close. We mentioned that the alloy of the engine parts can be affected by thermal expansion in different ways, therefore the amount of correction factor to the lash setting depends on whether the cylinder heads and block are made out of cast iron or aluminum. 

You can take the "hot" setting given to you in the catalog or cam specification card and alter it by the following amount to get a "cold" lash setting. 

With iron block and iron heads, add .002" 
With iron block and aluminum heads, subtract .006". 
With both aluminum block and heads, subtract .012". 
Remember this correction adjustment is approximate and is only meant to get you close for the initial start up of the engine. After the engine is warmed up to its proper operating temperature range, you must go back and reset all the valves to the proper "hot" valve lash settings.
