I say get some SS springs and fix your pinion angle first.

Agreed! Keep it simple. A set of 002 003 Superstock springs are less than $250 and the correct length shocks will make a world of difference. Then check your pinion angle and adjust as needed. If the car sits too high you can also get adjustable front spring hangers or flip your existing hangers. There should be no need to get fancy at this point. There are plenty of guys out there in A, B and E bodies running into the 10s with SS springs.
