looking for some input on blower

Im looking for some input from you guys on installing a blower on a stock 355 chevy small block.im looking at a 177 pro street blower. with a 750 blower carb.i have flat top pistons,stock 72cc heads and a 280h cam.im planning on running about 5 lbs of boost.I plan on building a better motor down the road with forged dished pistons and blower cam.the motor is in my 45 ford truck.I dont have alot of room in front of the motor.i can run a short nose drive if i use a short water pump,this would work better for me,has anybody converted to a short waterpump from a long pump.and what brackets can i use for the alternator and powersteering pump .i dont have room to run the alternator lower due too the motor mounts.looking for any input on this setup you guys or gals might have thanks alot
