Yes but it will mess with your boost. I wouldn't recommend it. You will lose more power with the boost drop then you will gain with the pullies.

Nope!!! Will still run but get less boost then with stock pullies. The boost is determined by the crank pulley to S/C pulley ratio. UDP's bring that ratio closer to 1:1(bad for S/C). I was thinking of buying at 10% overdrive pulley to help avoid belt slipping and increase the pulley ratio. That is why everyone buys a smaller pulley for their S/C because it will spin faster and have an increased ratio of crank to S/C pulley....

Should i leave the boost at 10psi?
being so close to maxing out the stock bottom end. 450whp is riding a fine line right?

Your stock crank will handle that. What you need are forged pistons & rods.
