A few years ago, a friend of mine used an autozone short block for drag racing. Lasting him about 2 years of racing every weekend and drove it to work. I would say a 600 to 650 Hp build.
200cc dart heads, compcam 292H, Victor jr, 750 DP, 300hp shot N02, 3500 stall, and 4.56 gears.
Finally developed a rod knock after eating 20lbs of n02 every week for 100 weeks.
