Hill’s Rod and Custom Autocross C5 Blazer

January 14th, 2023

What would possess an individual to try and make an autocross vehicle starting with a 1970s era C5 Chevrolet Blazer? If you consider the dual nature of the C5 moniker, as it pertains to this project, the riddle becomes a bit clearer.

You see, this build begins with a C5 Corvette chassis. The K5 Blazer body was cut and modified to fit the sports car frame. The fenders were also stretched and widened to accommodate the massive (19X12 on both ends) tire/wheel combination. Speaking of wheels; they are Toploader from Billet Specialties wrapped in 315/30R19 tires. The hood is carbon fiber and yields a weight savings of approximately 50-pounds.

Under the hood is an LS7 7.4-liter big block engine built by Schaefer Racing Engines. With a belly full of premium internals and a set of tricked out cylinder heads, the massive mill churns out 737hp to the crankshaft. The manual transmission, rear end and rear suspension are stock C5 Corvette. Exhaust has been modified slightly and this thing sounds great.

Fully adjustable shocks adorn all four corners, and the brakes are from Wilwood.

Time for a test drive.
