My honest opinion is that if you want round after round reliability you need to coin up for it. Cheap stuff can work but often doesn't offer the same potential.
The last BB I played with was in a back halfed 71 dart with a ladder bar and 31x10.5's, a cage and a diet. With a simple +.030 440, a mopar stage 6 head and a 1050cfm Dominator, a MP 590 cam, BME aluminum rods and 12.5:1 we were very consistent 10.30's at 136-8. It would 60' 1.40 on the back tires before the wheelie bars were added. I miss that! Cutting the brake loose at 4200 was a blast :glasses7:
