Your thoughts on low lash Camshafts

[priobe]

Just curious,

I was wondering your thoughts on a low lash camshafts. I noticed that the camshaft with low profile lash are adjusted to .010 hot.

Well, when cold with aluminum heads / iron block the lash is about .025

So, your cold lash can only be min or max adjusted to 0 lash when cold.

This will allow your lash to grow to .008 - .009 lash

What are you thoughts

Not much of an issue with iron block-head combo's, lash doesn't change much

With aluminum heads- iron block, at about 70 degrees, expect about .007" looser lash at operating temp, so set lash that much tighter with engine cold.

With all aluminum engine, about .015" looser lash at operating temp.

I have found it difficult to try to start my engine at about 40-45 degrees ambient temp, when lash is probably 0 or maybe less when cold.
