350 chevy... Pro-Action 220 CC straight plug heads, 9.39:1 AVERAGE static compression ratio - MSD Digital 6+ ignition & Blaster coil - AC Delco R43TS Gapped @ 0.055 in

on a side note after extensive dyno time with the race car (sbc) we found that champions actually developed the most power... we ran a gamut of plugs.. ngk, champ, autolite, ac, accel, splitfire... but i have heard of high fallout for brand new plugs being bad from Champion... i want to get my hands on some Denso plugs though..

anyone know the cross reference from AC R43TS to Denso right off hand?

and as with a lot of mass produced parts.. only a few companies make things... example, there really only 2 lifter manufacturers, a couple of major spring houses (valve springs) and a handful of valve manufacturers in the world... wonder how many name brand plugs are all made by the same supplier...

NGK UR5 in the 383s with Dart Iron Eagle heads. Also run the same UR5 plugs in the 302 Ford powered 16, and Accel #139 (13/16 hex and gasket), which is relly a Denso plug, in the 383 with the old 2.02ed 441 heads in the X-18.

I also like Warstiner, Red Hook IPA, and Hurrican Reef Pale Ale. :D
