  1. Is 32 degrees of timing at 14 psi safe on 91 octane with this engine combo running at full operating temp on a warm day? Do you use a knock sensor for pump gas tuning?

  2. I have a Procharger D1SC on my forged internals 4.3L V6 Vortec. I have been limited to a 6 rib serpentine belt. I would love to know where I can get an 8 or 10 rib pulley kit for a Vortec V8/V6 engine (PS, AC, Alt, Water Pump, Crank, tensioner) that I see on this engine in this video. Anyone know a good place to buy this? Thanks.
