600 CFM, all I need. Check my math!

So you drove over to Summit and got it, cool!
If you don't have to change jets, you can test several combinations in one outing. Takes seconds to change rods and springs once you get the hang of it.
Cross reference the different model's venturi, jets and rods, do a little math, and you will find you can do a lot more than the dots shown. I didn't have an AFR meter, but I had fun messing with mine.
Good luck!
