ok it does sound like you do not have enough initial timing advance.
if your distributor vac.adv. can is tight against the blower,
you might want to put/move the plug wires back 1-terminal in CCW direction looking down at the cap.
this will allow you to advance the distributor more to reach the correct initial timing advance...

insure you keep the correct firing order and separate the #5 & #7 plug wires, they are prone to cross-fire...
obtain a timing light and check-adjust the timing for 12*-18* BTC for starters.
what type of distributor do you have: stock or aftermarket?
delco-remy sounds stock = but is it an HEI or does it have points?
you will want to limit the total timing advance to 28*-34* based on the boost psi level...
