— The Proworx Difference

Why ‘Off The Shelf’ Isn’t Good Enough

When you’re building a project car — whether it’s a 1972 Chevelle, a classic Mustang, a hot rod, or a purpose-built street machine — the engine is the heart of everything. Most builders settle for a generic crate engine built to average specifications for an average customer. Proworx Performance Engines exist for builders who refuse to be average.

Built in Edmonton, Alberta, every Proworx engine is custom-spec’d around your build, your horsepower goals, and your personal style. You choose the displacement, the valve covers, the colour, the finish — and work directly with our team to dial in the right combination for your vehicle.

“Most crate engines are built for the masses. Proworx builds yours. Custom-spec’d, customer-controlled, and dyno-proven to outperform the big-name crate companies.”

The result is an engine that doesn’t just fit in your car — it was designed for your car, assembled by hand by master engine builder Len Feschuk, and verified by our in-house dyno before it ever leaves our facility.

"Fern and the team were amazing to deal with. Purchased a 496 stroker for my 1972 Chevelle and picked it up in Calgary. Done on time and any time I had questions he answered me. Excellent service in my book. Dealing with them was no stress and I couldn't have asked for more. Thank you so much Fern and the rest of the team. I will be seeing you guys soon. Will definitely be buying parts from them in the future."

5-Star Goole Review:
I finally brought in my 1988 Chevy 1500 truck to the west end JBs for a full-on engine swap, cooling system upgrade and full fuel EFI system upgrade. Byron, Fern and Ian were some of the best guys to work with on the whole project. ....
Fern was my engine builder who produced the torque monster that I’ve been wanting since 2001. Not to mention working with my OCD on blinging it out (not his taste, lol). I know by taking his advise to go for a quality build would pay off in the end. ....
