Then, the NGK BPR6ES (long reach) is what you need. The BP6ES (non-resistor) is NLA. The old Buicks used a BP5HS (short reach & one step hotter).

BP6ES is a safe choice.

I changed to BP5ES in my 3.5, but it spends most of its time poodling.
My carb, btw, 83 primaries with 7057 needles, 80 secondaries.

Haven't checked the timing for ages, but probably stock.
If your timing is advanced, best stick to BP6ES.

Can you still get non-resistor NGK spark plugs, Ivor?

BP6ES.. Yes, Carl, I can easily get them through eBay and various retailers.

Are they out of production?

I can't find them here. The NGK website says that they have been discontinued.

Item has been discontinued. This product may be used as a replacement:
NGK 7131 BPR6ES Nickel Spark Plug
