power valve block off

If you are gonna be doing mostly street driving, put a power valve in the primary side. It's purpose is part throttle operation; street driving! I can't say with certainty what will be exactly what you need, however a start would be a 6.5 P/V and drop primary jets 4 sizes from where they are now. It would be helpful to know what your idle vacuum was before you started. That information would lead you to P/V selection. To be sure it's gonna be trial and error.

Good luck.
