What heat range plugs???

BoveK · 06-06-2001, 04:28 PM

anyone have any suggestions for plugs for my car. It is a 90 GT with edelbrock performers, 1.7 RR, 65mm TB, 73mm MAF, GT-40 intake, e-303 cam, 24lb injectors, 155lph fuel pump, adjustable FPR, crane HI-6 ignition, PS-91 coil, Compucar wet nitrous jetted for a 125 shot. What heat range plugs should i get...and what gap should i set them at?
Thanks for the help

I use ac delco R43xls in my 6037 edelbrock heads. They're one heat range colder than stock, so they're good for juice. I've got a NOS dry kit with an 80hp shot (125 soon), and was told to gap them at .045".

You'll have to experiment a little to find out what's best, but that should be a good start.

This is like the basic rule : If you use a power adder, go on range colder plug (to start)and close up the gap. .035 to .040 is what I would do. The brand is your preference.
