Timing Curve

[jvest]

Let me know what you guy's think about the timing curve. I've not tuned the mechanical or vacuum advance yet. I'd like to get some opinions on a starting point for my setup. I started with 35 deg total, but pinged a little. I lowered it to 32 deg and I'm not hearing any ping.

Current Timing Curve:

• 20 deg initial (sounds high, but is due to mech advance only 12 deg)
• 32 deg total @ 3000rpms (12 deg mechanical)
• 45 deg total @ 1000rpms w/ vacuum advance (25 deg vacuum)

Engine Setup: (68 Camaro)

• 383 Gen 1 SBC (.060 over) Eagle rotating assembly
• 2 Valve relief flat pistons
• 5.7 rods
• Bowtie Phase 2 heads fully ported and shaved to 58cc
• RPM Performer intake
• 284 Comp Xtreme flat tappet hydruaulic cam
• 750 Speed Demon carb
• MSD 6A Ignition w/external coil HEI setup
• 350 Turbo w/3000 stall
• 4:10 rear gear

Thanks for the help,
Jim
