What are some good plugs?
Bob Kurgan told me to get the NGK v-POWER plugs.
I have afr heads but the part number for them was 4091 or Ngk r5671a-7
Not sure if that number will work for your heads though.
I run NGK as well. Can't remember the number though. It's 2 ranges colder than stock heat range.
I am just a lowlife overseas contractor who is all about the money.......
Either the NGK or Autolite Racing plug and like Larry said about two heat ranges colder than stock. Both the NGK and the Autolite racing plugs are fairly easy to get about any store that stocks either brand can get them. If you go to OReilly's, they have will have an Autolite catalog, in that catalog is a section for aftermarket heads. Most every aftermarket head availible is in that catalog, once you find your head it will give you the plug number for that head. A lot of heads I did not think would be in there are in that catalog. You should still go at least one heat range colder than what is listed in that catalog for your head since you are using a blower.
The current combo is an '85 coupe with 302 bored and stroked to 364, Ported Twisted Wedge heads and a BXR intake, A9M ECM with a Moates chip, Doug Nash 5 spd, 4.56 gears, Hoosier 275/60/15 drag radials.
Daily driver '89 GT 302 stock block, crank, rods and pistons, ported GT-40P heads with stock valves, Ported Explorer intake, B302 cam, Z spec T5, 3.73 gears, Moates chip and no traction. Made 325 whp and 325 wtq.
Thanks guys.. Got some 4091 or Ngk r5671a-7 on order.. Will be in at 11:30 .. What would be a good sugested gap on them? I need plenty of spark, but don't want it so big that it gets blown out.
On my mod motor I run them at .34 with 14#s no problem NGK TR-6
Do you have a MSD?If not I'd recomend one. I run my plugs at .030Originally Posted by tollebuilt

yep yep...get a msd box or what not and run um around .030 gap.....no ignition box i had to run mine tight..like .o20 or the spark would blow out at 8lbs of boost.

I'd try .035. If thats too much go down to .030. I've always heard the NGK plugs work well on forced induction setups.
Thanks Mike.. Did the .035 and so far so good!
