No doubt about it: 583 lb-ft of torque at 4,600 rpm and 601 horsepower at 6,000 rpm are numbers that can make any vehicle owner proud. With an engine like this, a new set of tires might be needed every couple of months.No doubt about it: 583 lb-ft of torque at 4,600 rpm and 601 horsepower at 6,000 rpm are nu Some of my earliest childhood memories are of my father working on cars. For a few years it seemed we always had some other person's vehicle parked in our yard with no engine or transmission, while pop earned a few extra dollars spinning wrenches on those vehicles. As a kid, it was always exciting to play in and around these vehicles. They seemed like sleeping monsters. That same childlike excitement manifested itself while at Smeding Performance in Rancho Cordova, California. A built-to-the-hilt 383 with a stacked and polished blower and a couple of carbs appeared much like those sleeping giants from my childhood. It doesn't take much of an imagination to look at this engine and hear its throaty roar and listen to the supercharger whine. All this and it comes out of the box ready to run, just like a new pair of sneakers: lace it up and go. This build started out as a brand-new GM Performance one-piece rear main seal, four-bolt main block straight from the factory. Having never been touched or used, it's ready to be machined and clearanced for stroker use.This build started out as a brand-new GM Performance one-piece rear main seal, four-bolt m If you have not heard the name before, Smeding Performance builds solid dyno-tuned crate engines ready for nearly all applications. Ben Smeding also custom-built our 717-horsepower 572 engine that went into the Project American Heroes '57 Chevy. Since the theme this month is small-block muscle, we called Smeding Performance and asked if we could follow along on one of its blown and stroked crate engines from the initial build to the dyno test. A few weeks later Super Chevy was up in the Sacramento, California, area working with Smeding and documenting this buildup of a blown brawler in a box. Once the block is off the Rottler boring machine, the final .003 is diamond-honed with a torque plate for a final bore size of 4.003 for maximum cylinder wall thickness.Once the block is off the Rottler boring machine, the final .003 is diamond-honed with a t Since this is a stroked engine with a 3.800 stroked crank, it's necessary to clearance the bottom of the cylinder walls so the end of the connecting rods have some wiggle room at the bottom of each stroke.Since this is a stroked engine with a 3.800 stroked crank, it's necessary to clearance the Once the bob weight is tallied and the weights are installed, the crank is spun by Dan Moody to achieve that perfect balance. Moody balances the entire rotating assembly to within half a gram difference between each component.Once the bob weight is tallied and the weights are installed, the crank is spun by Dan Moo 1 | 2 | 3 | » | View Full Article By Mike Harrington Enjoyed this Post?
