75 280... What plug to get?


Recommended Posts

I did a search, but didnt find quite what I was looking for.. I am looking for some ppl with a similar setup to mine (or someone who just .. knows! :lol: ) to tell me what spark plugs I should be running. Im convinced that I should rip out the Champion's that are in there right now and go with NGK's.. but what p/n? And what gap should I set them to? My car is a 75 280 (stock L28) with 72 SU's and no cat/mufler. (well, I dont clasify the 'cherry bomb' glaspack as a mufler!)

I am tryin to get this thing to stop hesitating/boging (idle to about 2500) and running so rich (all the time.. stinky) I think some good plugs (and a new air filter :oops: ) might make a diff here... Anyone running a similar set up?
