Justin, there is no way of really guessing at what power it makes as it really depends on how it's setup and there are a ton of settings to do. You can either make or break a stock transmission with a #10 but it is the plate of choice for a stock auto, now having said all that there are folks that say you can't make big power with a #10, the main thing is it's all in how you set it up and yes real good power can be made. The main thing with a #10 is the smooth transison(sp) on the bottom with a tad of de-fuel on top to control EGT's, in my opinion a 10 should always be with a set of 3K's and a bigger housing or modify the stock setup to get more air out of the motor.
