Not Ranked
The 6AL has revlimiter chips for different "redline" to prevent overevving your engine---for $50 more it could save your engine if you missed a shift or wrapped it up too far before upshifting. The different limiter chips are available from MSD. Cheap insurance.
The 6A will cut out ignition to a point but not as effectively as the 6AL.
Also go with the MSD Billet distributor. I have a 289 with all MSD ignition, 6AL, Blaster coil, billet distributor, MSD plug wires---works great
