ADDING A BLOWER TO A CARB MOTOR?

[Coupe Devil]

Ok I was told I cant get a 8-71 for a 302. That may not be true? I understand why the air should go through the top of the cab now but wouldnt haveing an 8-71 be the same as my "spacer Idea" since the carb is on top of the blower. I have a greater availability of performance parts for a 460, I can build a HOT 460 short block for $1000. Using a buddys spare parts. Would going with the 8-71, all I would have to change is the lower intake to go to a 460?
