How do think this cam will behave in 408 ?

I’m not sure it’s even a third of the piston. It may not even be a quarter.

It’s a third or better but don’t think it will make a difference.
Think of how much oil is on a piston due to windage . I doubt it will make difference on a motor that spends most of its time under 4000 rpm .
