Hughes cam?

I think the post you're referring to said 102 ICL (intake center line). ICL is different than LSA (lobe separation angle) I think. I agree with your premise (tighter LSA is better for under-valved engines), but is there a company that would even grind a /6 cam on a 102 LSA (and be able to get it to me by end of May)? Not sure if a regrind can take a 108 LSA all the way down to 102 - that's a pretty big change.

No, Bewy has it right. He’s talking about LSA not ICL. He knows the difference.

The biggest thing about getting a 102 LSA or the tighter ones like Bewy mentioned above is getting cores that will take an LSA that tight.

Cam cores are cast with the lobes roughly in place. And you can’t go very far one way or the other once the core is made.

There is more than one reason why the de facto LSA is 110. And that’s most economic.
