1972 Jeep CJ with big block Chevy at SEMA 2017

LAS VEGAS, NV — Being at the SEMA Show is essentially one continuous “Well there’s something you don’t see every day” experience.

And sometimes, in a sea of head-turning automotive (and otherwise) wonders, you’ll find something truly unique—at least for those of us accustomed to driving only on pavement.

The “Blue Streak Beast” is such a thing. A freak, if you will. A monster.

It doesn’t possess the cleanliness of a Ringbrothers custom or a Lingenfelter Corvette. Just Frankenstein-like looks and terrifying power.

This Jeep CJ is powered by a 468 big block Chevy (which we’re assuming is a 454 bored 0.30 inch over). We’re especially fond of the hood scoop, exposed headers, and those ridiculously awesome paddle bogger digger tires on the back.

Here are a few specs.


  • 468 BBC
  • 13:1 compression
  • 585 horsepower


  • Powerglide
  • 4200 stall converter
  • Trans-brake

Rear End

  • Ford 9″
  • 35-spline axles
  • 6.50:1 gear ratio


  • 33” 13 paddle bogger diggers

This cool CJ is on display in the Hayden Automotive / Blue Streak booth, and includes some of their products, including a Hayden electric fan, a Hayden remote transmission oil cooler system, Blue Streak performance race spark plug wires, and Blue Streak boot protectors.

We love it when a plan comes together.
