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.
