Hi Gene,

Simple question for you on a solid cam. Lunati cams list the vavle lash as (example). Intake .020 and the Exhaust .022. Does this mean cold or hot, they don't say? Even on the spec card there is no reference, but other Manufacturer usually clearly state hot or cold or give both.
Any dates set yet for the car show?

Thanks,
Fred.

Those are always hot settings, well usually. Cold settings are typically one thou looser for cast iron heads/block ( lash shrinks just a hair when warm), and from 4-6 thou tighter for alum heads/iron block.( lash opens up when warm).

I always like to set them a bit tight for initial run in, a bit gentler on the cam lobes.

Show dates are 7/8-7/10. I had to pick a sunny, rain-free weekend! smile.gif

Gene,

Thanks for the data on the lash, I would have guessed wrong. Have the dates scribed into the calendar, I'll be there.

Thanks,
Fred.

Gene,

Are the dates for the Can-Am? I live right in Kenmore; I should be there this year. Last year I was away on vacation and missed it. If you need help with anything give me a shout!
