Spark plugs and gas
I am running typical Chevy 350's, mild cam, aluminum intake, and headers.
I have always used R44TS or R45TS plugs. When these engines were made and plugs were spec'd we had leaded gas and decent unleded. Now with 10% ethanol is there a better plug or heat rang to use to work better with the gas? This is street driving, car shows and cruises. No race track near me or I would be there. |
