Curious what some of you are using for spark plug make & part number? Application is 340 6 pack, 4 spd, 3:73 gears at rear, cross over plugged, 195 stat, stock grind cam. What else do you need to know? Thanks.

Compression ratio is what was needed for a proper answer. Aotolite 53 or champion n9yc

Just curious, the eddy heads wont accept the factory size hex on the plugs.
Ive had good luck with ngk
Did you use the NGK 2635 like the other A body members mentioned? Thanks

I used the NGK BKR5E, but that is for the eddy heads

stock heads can use any 3/4" reach gasketed plug with a 5/8" or 3/4" hex
Yes I am aware of that. Thanks for the info.

i'm running autolite 64 in the dart.. pretty much run a 63,64,65 with stock heads. i'd rather have the NGK but the place i was at didn't have them so autolite it was.

I do not have a radio so I run the non resistor plugs.
