Re: 550hp and 30mpg First Goal
Nice!
With regards to the Rhoades lifters, they depend highly on your combination as to whether they will provide any benefit. Generally speaking, they are most beneficial when you have a cam that's just a bit too big. But if you haven't changed your cam, chances are that your cam is well-suited for your combination. There are many reports of decreased performance because of the Rhoades - it just so happened that they worked great for me but they might not have the benefit for you.
And I'm still waiting for a way to be able to change an engine's running temperature - run it hot for regular driving, then run it cold when you want some racing. I think a hot engine goes a long way toward MPG. I've visualized a way to have a dual-thermostat engine (a 160- and 195-degree thermostat in parallel with a valve), but I haven't ever been able to get it drawn up for production... Oh well. In the case of temperature you can't be blowing engines so safety does trump performance (unfortunately).
