Any suggestions on what spark plugs to use in my GN? Stock long block, 50 l.b. injectors, turbo tweak chip 20 p.s.i. and alky.

I use AC delco...stock plugs, they work fine.

or try the CR43TS, same heat range as the R43s but commercial 'grade', a bit more heavy duty they say

I use 42 or 43 TS gapped at 30 or 32... ( I do this alot and I can never remember...) Delco's are always fine for the TR
