I think you have WAY too little clamping to hold the blower down. These things take a lot of horsepower to turn and therefore will apply a lot of torque to those four little 4-barrel bolts. Also, the outlet of the blower is a big long rectangle, not a small square hole - so you'll severely limit the boost potential. BUT - if all you're going for is 'blower looks', then maybe it isn't an issue for you.

Me, I'd machine the heck out of the manifold and weld up a mounting structure to solve both problems . . . or buy a 4-71 blower manifold that is designed from the get-go to work.
