what secrets you keep talking about??? Verse my LA 360 in my Duster, the 5.9 will have better heads (magnum heads), the cam has more lift/duration, it will have better compression, and a lighter rotating assembly. Is this a speed secret or something??? Is it a speed secret that 3.91's or even 3.55's is better than 2.94's in the 1/4 mile?? If I dropped this motor and gears in my Duster, I'd sleep walk well into the 12's.....
