447 HP Vortec Small-Block Build - Budget Sledgehammer

There was no shortage of enthusiasm for this little 350 when the power numbers came to light: 445 lb-ft of torque at 4,400 rpm, and 447 hp occurring at a peak power rpm of 6,200 (using a set of 1.75-inch long-tube dyno headers). A study of the power curve shows this combination comes on its torque curve very hard at about 3,000 rpm, and then keeps coming like a sledgehammer. The horsepower curve hangs further than it has a right to, considering the simple components-but darned if it doesn't hold to well over 6,000 rpm. Add up the torque and surprising high-rpm capabilities, and you'll get power output that simply can't be denied.
