1955 Chrysler 300 426 HEMI Build Project

The Roadster Shop took the wraps off one of their newest completed projects, a 1955 Chrysler 300. The car sits on a modified FAST TRACK chassis which includes an IFS and four-link rear suspension with upgraded Baer brakes. Under the hood they installed a 6.4 L Gen 3 HEMI V8 which was increased to 426 ci (6.98 L). To help the engine appear like the original 5.4 L Gen 1 FirePower V8 they created custom valve covers and adapted the original intake system. Behind the engine sits a GM 4L80-E four-speed automatic transmission connected to a Ford 9″ rear end.

Very nice. Looks good from here in Alabama. A new 55 300 426, better than factory. If you, or whomever owns that car, sells it, I bet it would go for a little more than it sold for initially in 55. I am going out on a limb here, and think it would sell for at least 6k. LOL

james briggs says:

very cool build. it looks like a 3rd gen hemi with 1st gen valve covers. how did you get the cubes, or did you get a crate engine. im also glad to see you put a four speed trans in it. very cool build indeed. also how much horse power does it put out?

John Behneman says:

Wow!!!! I am impressed. A Chrysler 300 resto-mod. But it looks totally original. Yet outperforms the original in every way. Way to go!!!!! That is what hot rodding is all about. Take the best of the old, and blends it with the best of the new. Thanks for sharing something different. I love it!!!!

I have always loved this car. I wish that Chrysler had stuck to this vision throughout the life of the 300 series.
