I run a B-31 in my blown 331 car, But before adding the blower I ran the set up NA for about 8 months. Combo consist of dished pistons for 8.5:1 compression, TW heads, E-brock RPM intake, 70mm TB, shorty headers, 30# injectors, AOD with 3.55's. Never had it dynoed but it ran pretty good being set-up or boost. On 245/50/16 Nitto DR's and a 3450 race weight it ran a best of 12.78 @ 106 in the 1/4 and 8.14 in the 1/8.
