6-71 Blown 408/416

Hey tech is tech! Im running a 8-71 on a stroked 360, 3.79 crank with -30cc dished pistons for 387ci and 8.5 cr. The 4" cranks require a REAL deep dished piston to keep a low cr. And an 8-71 on a sb requires a 'retrofit' blower to clear the distributor. This is a blower assembled backwards with the case extension facing fowards. As being the 8-71 is 1" longer than a 6-71, the snout length is shorter on a 8-71 too.
