      E85 Timing for Procharged 383

      I just installed my D1SC Procharger on my 383 SBC. I'm trying to figure out a safe timing table for it. I'm also running Holley's HP EFI MPFI kit. I data logged 6.5 PSI. Here's some specs on the motor:




      Cam Specifications
      Int. Lift: 510
      Exh. Lift: 510
      Duration @ .050: 244-244
      Lobe Seperation: 108
      Advertised Duration: 318-318
      Cam Idle: Rough
      Torque Range: 2500 to 6500


      Head Specifications
      Aluminum 10:1 Compression
      Chamber Size: 64cc
      Int. Valve Size: 202
      Exh. Valve Size: 160


      Here's my current timing table.

      It's enough timing for it to run good, but I have no idea if it's safe or not. I need some expert advise.
