thanks. '68 crewcab w/3.2 (46mm Webers, HPV-1, SSI's & sport muffler) & 5 sp. |

I'm partial to the NGK V-power plugs myself. You'll want to be careful that the electrode depth matches your current plugs.

NGK - BPR7ES - the R designates a resistor. Go the 7 heat range.

I use the 8 heat range to be safe, but if you're not in a high-compression low octane situation where detonation is possible, 7 is better... 9 was way too cold, fouled all the time.

Gumba,
If you experience plug fouling, you could try hotter plugs. I run NGK 6's on the track and around town with Electromotive XDI and 50 mm PMO's on a 3.6. Plug readings look really good! Another reference is PMO's suggestion: Around town and normal driving NGK BP5ES up to 9:1 CR, and BP6ES for higher compression engines. Leave the gaps as they come (.028). Take plug readings to be safe. Lyn
