Review on Competition Cams 6100 Magnum Chevrolet by John Miranda

Revainrating 5 out of 5

BEST MATCH-UP CLASS for ZZ4 Small Block Chevy.

The first thing to upgrade isn't the timing system. You can spend your money on the cooling system because what kills your engine or transmission kills heat. I have a second BE COOL radiator and they fit and the finish is always nice and cool. But you should always ditch the fan and fan clutch and throw away some 12" SPAL dual electric fans.

Pros
  • Great design
Cons
  • Zero
