my Low dollar 318 hop-up project
Looks like you opened yours up on the intake side much more than what I did. You need it, cause there is no air in Colo Springs, I've been there a few times....... LOL
You did nice work, although I personally don't like to go that thin around the valve guide on a street car, always worry if it should form a slight crack that would lead to a "chip" or "flake", it would be going straight into you cylinder.
I actually considered buying that car when you had if for sale here a while back, but since bought another Duster...
