I have a 91 s10 with a stock 350(8.5:1-CR) with a elbrock intake, 650 holley, headman headers, full msd with the stock heads and cam.

I going to run a 100shot of nitrous with plans to run between a 125-150shot later on. I was wondering what a good plug to use? From reading the sticky the ngk tr6's gapped around .035-.038 look like the plug to get but with my CR being so low do you think I could run a 5 heat range

thanks for any help

 

Which heads are you runnin?? Alot of times if you call the tech line at say afr or edelbrock the will sugest a plug for your application. Im almost positive a tr6 wont work but im not 100% sure
