as for the timing - i've had it everywhere from the stock Z28 curve to locked out at 36- it does very little to solve this issue - with or without vacuum advance.

If you are sure it's not a carb or timing issue you could spend some time looking for an air leak elsewhere, maybe the intake. I think a .031" is the largest squirter I've ever used. Not crazy about locked timing on a street car with a relatively mild camshaft.
