I have no idea of how you are driving the car on the street now with available pump gas.

As mentioned, ethanol laced fuel and heat soak are your main concerns. That big a$$ ACL ASSY also acts like an umbrella and won't allow engine heat to escape easily, especially after shutdown (heat soak).

11.4 to 1 CR and a very aggressive timing curve (all mechanical with no vacuum for the street).

I have seen these 5 GAL cans in gas stations close to race tracks.

If you want a true street driver, maybe consider building a mild 390/428 for the street and use the 3X2 with carb or TBI if you want the wow factor. Store the 406.

Who makes the other 3X2 TBI setup?
