yes. As for the start/retard box, Locking out the msd distributor and setting it @ 35,37,43 degrees etc.. makes engine almost impossible to start especially after its up to running temps. The start retard box initially drops the timing down to say...6-8 degrees @ start up, and will remian there until engine rises above idle, then it will go back to your preset locked out timing.
Doing this allows for you to make more consistent runs, confirm timing is where you need it to be, eliminates playing around with different springs,spring failure on mechanical advance or vaccum issues on vaccuum advance distributors.
Also works great when running nitrous and you need to pull 4,6,8,12 degrees of timing, you can just set it to the desired timing, and elimate the extra $ & time wiring in retard boxes for the nitrous(allthough most are plug n play)
