Being based out of Northeast Ohio can be a bit of a drag if you’re heavy into the car hobby. Located smack-dab in the middle of the Rust Belt, we get the worst of Winter; snow, ice, salty roads and below freezing temperatures. All of the tracks and dragstrips are closed, outdoor car shows are nonexistent and you may see one or two interesting vehicles throughout the Winter months.

However, that doesn’t persuade us to throw in the towel until Spring, nor does it deter us us to keep working on our projects through the rough and tumble of the Northeast. In fact, quite the opposite. It seems that just before winter had hit, a new speed and performance shop has opened, started by Chuck Fitch–a long-time speed parts specialist and Chevrolet Performance parts dealer.

Dubbed Ohio Speed Shops, Chuck’s new hot rod haven is set to offer gearheads all over, a new outlet in which to order the latest crate engine or speed part. His first creation, is exclusive 525 hp LS3 crate engine, that packs a self-learning EFI system from FiTech. For only $8,679.99, you get a high-10 second capable crate engine with 100% street-ability. Chuck sent us the entire breakdown the other day, and we passed it along for you below!
