318 MSD 8388 distributor

Post #4's question is a recurring question/problem on this site & others.
[1] If you using the same coil that was used with the Bal Res, then the BR must be kept.
[2] If you are using a new/different coil that does not require a BR, then the BR is not needed & the wires can be joined together. Two excellent & cheap coils that you could use here are the MSD #8207 or Summit # 850500. These will give more spark output than any canister coil & maximise the benefit of the R-to-R dist.
[3] The new dist requires full 12v. If a BR coil is used, the wiring is a bit tricky.
