Cross fire ignition wires

Refresh my memory what ignition wires do you have to keep away from each other to prevent cross fire..322 nailhead

If you are using the spark plug covers you need the picture in the manual to describe this. But you can isolate each wire under the civer using the small diameter plastic wire loam. In that case placement doesnt matter. I sourced tge plastic wire loam @ Walmart in the auto radio section. Its very cheap and I used it almost to the distributor cap. Worked great!

Not an issue if wires are new, gap is no more than 0.035" (with the stock 7 mm wires), wires do not touch when parallel (ok if right angle), and are correctly attached to plugs and distributor.

Rule of thumb is if there are two cylinders on the same bank firing consecutively, the wires should be non-adjacent to each other eliminating potential cross-firing, engine missing, and/or short spark plug life. Since the firing order for a Buick 1953-1956 V8 engine is 1-2-7-8-4-5-6-3, wires #8 and #4 on the driver's side bank along with #3 and #1 on the passenger's side bank should be separated.
