225 /6 at 250HP?

That is one beautiful setup.

Thank you for all that information.

So just to clarify a few things. I dont need to mess with the engine much (just larger valves).

But, it is crucial to get the AF correct to both get the most power and not lean out and burn valves.

So if I modified the Holley 2300 (500cfm) I have sitting on my Scout that would be an almost perfect carburetor to start with?

And the O ring cutter, that I am guessing is for the Oil cooling lines to and from the turbo?
