Hot Rod Power Tour 2023

Speedway Motors did the 2023 Hot Rod Power Tour, and we're back with some stories and photos from one amazing adventure

Model A Coupe Hot Rod

From the Model A coupe body to the dropped axle and chrome OEM wheels. This car project is a basic, but cool traditional hot rod. Comparable to the American Graffiti coupe. Read more on how to start planning your hot rod car build.

Tim's Model A Roadster Hot Rod

Tim Matthews has been collecting pieces for this hot rod for a long time. Here's the amazing story in his own words...

Model T Roadster Hot Rod

Doug Siemen's Model T is a cool little hot rod. It's even better when you learn that it was built from scratch for a great cause. Check it out!

Model T Sedan Hot Rod

That flathead engine pictured on our street rod catalog cover is just one little piece of a pretty mean little Model T hot rod. Check it out.

Mick's 1930 Model A Roadster Hot Rod

This hot rod was built to be driven, and there are some neat tricks and great pieces of history hiding in plain sight!

Jess and George Gasper's Model A Hot Rod

This Model A coupe was built with family, friends, and a lot of heart.

First Drive: Tim Matthews Model A Hot Rod

Tim Matthews has been working on his hemi powered hot rod roadster for a long time, and just recently got to drive it for the first time. Check it out!

Solid Axle Choices for Your Traditional Hot Rod

When it comes to a traditional style build on an early hot rod it just has to be rolling on a solid front axle of some sort. In this buyer's guide we take you through I-beam and round tube solid axles, spindle choices, radius rod needs, and more.

Modifying Axles to Lower a Hot Rod

Learn how to lower a hot rod by modifying the axles and some history behind early hop ups. This project features a Ford axle with wishbones for a Model A.
