I have a Crane cam #521211 in my cleveland.
It says to set the lash hot at .026 so .028 cold should be close enough.
I have tried this and the car runs fine but I thought I might try playing with the lash a bit. I will be setting it cold this time so,I figure .002 with cover the difference from hot to cold. Would you try .024 or .030 cold! What do you guys think?------------------

Why not just warm it up and set the lash "hot"? I don't think you can guess what it'll be cold.SteveW

I think you missed my point.
I would like some information on how changing the lash will affect performance and how much I can change it either way?
I know with cast iron heads and a cast block its approximately .002 difference from hot to cold.

.002 won't make much of a difference.
.005 to .010 loose will pick up the bottom end.
.005 to .010 tight will pick up the top end.

I will try .023 for starters and see how things go. Just wondered how far each way I could go.
Thanks
