I guess I will add my $0.02 worth of experience.

We have run a 1969 small block Barracuda since the late 70's. From the start we ran the A body SS springs. (002-003).

They worked well but would become inconsistent until we replaced them.

We probably went through at least three sets of the springs until we converted to the Caltracs bars and springs.

The car became more consistent and we had to adjust for wheelstands.

My advice would be to to directly to Calvert setup and not use the Mopar springs.
