How much HP from SBM ProComps? Well... 670HP!

The same daylight under both front tires is a good sign. I'm not partial to so much rise in the rear - make sure the shocks have enough extension for what you have. The 2nd picture looks like the tires slightly unload compared to #3.
And don't sweat the difference in horsepower. Dynos are not reality and horsepower numbers off them mean very little unless you're selling something. You've got a good engine there.
