hey guys i'm building a 351 windsor stroked to 445 ci. it will be supercharged with a ysi vortech making about 20 lbs of boost. are xp 3924 autolites a good choice and what gap would be proper for that boost
You'll definitely need a hotter ignition system. I wonder if Kenne Bell makes a boost a spark for your application. Their boost a pump has been trouble free on my car with the stock fuel pump and its 109,xxx miles.
