A Crower-injected ZZ4 SBC...
A Crower-injected ZZ4 SBC is a far cry from the original six-cylinder Cummins diesel.
Now, a vintage trailer truck may not be most people's first choice for a radical street rod, but then nobody ever said that Crosby is your typical fabricator. And if ya think about it, the majority of the hobby's most memorable street rods were built by those who think outside of the box. The only box we envision ever relating to this "Crosbybilt" may well be labeled Revell or Monogram.
