To much?

Im building an 8-71 blown sb Mopar.

The 8-71 in the pic is a standard 8-71 blower.
You need a "front offset" 8-71 blower. What this means is that the blower is assembled backwards, with the case offset to the front of the engine. This results in more distributor clearance and a blower that is centered better over the plenum, for better A/F distribution.
