As most of you know, I hurt a piston in my Malibu’s 421 a few weeks back grudge racing a 557ci Big Block Malibu at National Trail Raceway during the JaxWax Street Madness Event. Totally my fault. The car ran 10.50’s at 126mph a week later and showed no sign of an issue. Until it started huffing out the breathers. But, thanks to “Uncle Bob” my 421 is back, better than ever! Check out the first test drive AND our progress on the 55!
