Super tuning car runs good shooting for great

I had trouble getting my 340 to run with vacuum advance without pinging with my last cam, [email protected] solid cam 106 LSA, installed at 102. It had 185 psi cranking pressure. Never did get it to work without pinging, new cam is 252 @ .50 but on a wider 110 LSA, in at 106, and actually acts a lot smaller than it really is. Going to try out the vacuum advance with this cam, limiting the amount like shown above, after I check cranking compression.
