"With the stock 10.0:1 HiPo pistons, I have zero evidence of detonation or pinging. For ease of starting and to reduce the load on the starter I have the msd box set for a 20 degree start retard".

I only have an older MSD 6 (non digital). Can you explain the 20 degree start retard function of the digital 6 MSD please - I might look into getting one.

The manufacturers specs on my Roush engine call for 18 degrees at 900 rpm initial timing....
