Title: Which plugs?
Post by: 76k104x4 on February 19, 2012, 09:48:14 pm: First off my 76 K10 has a 350 with a mild cam and a Edelbrock 550 carb I have long tube headers and a Accel distrubutor I have been using the Accel shorty header plugs but I've been hearing bad things about them I was told those where the only plugs you could use with headers due to clearance so basically I'm wondering what you guys with headers are using BTW my headers are the 100 dollar Flowtechs you get from Autozone thanks guys

Unless you have a built engine I have never seen a difference between the $2.00 and the $9.00 a piece spark plugs. I just go with a good brand and use what is designed for the truck.
A lot of people get suckered in to buying expensive plugs when like I said, if it is not a built engine it doesn't make much difference in my book.

Post by: SAATR on March 13, 2012, 01:58:22 pm: ACDelco CR43TS or NGK UR4 if you still have the factory style heads. TR55 if you're running vortec heads.
