Chevy Small Block Part 22 - PT. 22: Horsepower Is King!

The Right Combinations Are The Key

By Mike Petralia

While some racers would jump for joy at such an increase, and we're certainly not putting it down, for the time, effort, and expense of the swap the results were not worth it in our minds. All that means is that we've pretty much hit the wall with the current parts combination we have and just like on the street, throwing bigger parts at it won't make it go any faster. So we're rethinking our strategy and planning some cool stuff in the near future. We're confident we'll see close to 600 hp by the end of this year, still on pump gas, too. But while we're not totally sure we can get there from here, one thing we are sure of is it won't be easy, but it'll sure be fun!
