gonna run the valves tonight but its snowin and mid 30 so i don't really wanna start it. if i have to i will but perfer not to. it says .010 I and .012 E hot. what should i set them at cold?? whats the adjustment differance about cold to hot?

that lash seems tight.... block and head material are needed for you to get an answer really...

thats what i thought when i put the cam in it last year but thats what the card calls for. sorry bout that did forget to mention that. cast heads.

did it call for 10-12 thou cold ??? Give a call to that cam company and confirm that.. That might be a cold lash setting also.
I cant recall a solid roller cam ever being that tight on lash.. even tight lash cams are in the .018-.020 range.
If that was all aluminum wedge (Maxx Block) and Indy heads, you couldnt even achieve that those settings, if you wanted to. That tight of lash set hot would leave the valves open once it cooled... fact.... They grow about .015.. so it wouldnt even start once it cooled down.
I dont care what the cam card calls for I wouldnt run the tighter than .018-.020

I bet its a cold setting... thats about right for a aluminum head big block with a cast iron block...
it would grow .006-.008 so you would be at the .018-.020 as mentioned.

Drag 'er down to Death Valley. It's 101 there right now. Perfect weather for runnin' valves.

Iron block with iron heads set them .002 looser when cold, per the Crane Cams catalog instructions for setting vavles when cold It works for me, check and reset them when hot

FWIW I set mine at .012/.014 Stage VI heads Iron block solid roller cam and when I started it it sounds a little more nosiey than I thought it would. If we ever get some good weather I'm going to set them .016/.018 warm. 10/12 seems tight hot. What does the cam card recommend?

.010 intake and .012 hot. lookin at the card right now. just set them tonight and it sounds great! cast 340 block and cast heads

Brian I always set mine at .020 cold. Make sure that both the Intake and Exhaust valves are on the base circle for an accurate setting. Hopefully we can get some warmer weather so the tracks can open up.
