Ohio Speed Shops Announces Their Dyno Tested LS 6.7L 570HP Deluxe Engine Package

If you’ve been a gear head for any length of time, and are now just coming onboard with building or dropping an LS crate engine into your hot rod, you seriously have some catching up to do! Embraced by most, and shunned by a few, the LS is basically the small-block Chevy of the 21st century.

In recent years, we’ve been seeing some rather radical LS swaps — some that were built in a way that, at first glance, they simply hadn’t looked like any LS engine we’ve ever seen. Now there are endless options out there that allows you to build something truly unique, usually by piecing it together. But more often than not, you can also scoop up a potent LS engine package that looks the part of a custom-built engine.

Such is the case of Ohio Speed Shop‘s 6.7L (408 cubes for those in ‘Merica) LS with 570hp on tap.

Official Release:

    Hello! This is kind of off topic but I need
    some advice from an established blog. Is it very
    difficult to set up your own blog? I’m not very techincal
    but I can figure things out pretty fast. I’m thinking about making my own but I’m not sure where to
    start. Do you have any tips or suggestions?

    Appreciate it
