Orange boxes are known for pulling timing out. I personally do not use them anymore.
Both of my cars have old MSD 6AL boxes and modified OEM distributors. A simple HEI is also under the hood that a few quick wiring swaps get back on the road should the MSD quit. Have not had a MSD fail yet.
If you are really super tuning you should check the rotor phasing. You can modify an oem rotor with an offset brass rotor tip.
