I have a alum Shelby block and Dove TP heads. I am running a Comp Cam solid roller and they specifiy .020 for lash and I am sure that is a hot spec, cam card does not say.

I always set my lash cold. Primarily because I am slow and the engine is cold by the time I get set up.

Question. Several guys here are running alum FE's with solid roller cam-probably even some with Comp Cam's Magnum roller, 308R.

What would the cold lash setting be if hot is .020. Expansion rates are differant for each block/head setup.

Comp cams will give me a big block Chebby best guess but I would like to see what the alum FE guys say.
