CT350 602 Crate Engine

The Chevrolet Performance CT350 circle track crate engine delivers competitive and durable power at an economical price. Karl Kustoms is now offering them as a dyno-verified package that is ready to race! Designed for circle track’s weekend warriors, this bullet-proof 350-horsepower, 350-cubic-inch IMCA-sealed racing crate engine (often referred to as the “602 crate”) is a tough combination of power and reliability – and it fits almost any racing budget.

Based on GM Performance Part’s popular 350 HO engine, the CT350 includes:

  • A brand-new four-bolt main block
  • 9.12:1 hypereutectic pistons
  • NEW!! Forged Steel crankshaft
  • GM iron Vortec cylinder heads
  • A high-rise dual-plane intake manifold
  • 8-quart single kick-out circle track oil pan
  • Valve cover kit with breather tube and breather
  • A special “kool nut” rocker arm nut design
  • HEI distributor, spark plugs and wires

The 350 HO’s unique dual-pattern cam is included, too. It’s based on the one found in 1965-67 Corvette 327 engines, but with more lift and duration to clear the engine exhaust quickly and move more air – providing excellent mid- and high-range power, where you need it on the track.

What’s Included

  • Fully GM assembled Long Block
  • Steel Valve Covers with Chevy Bowtie Logo Breathers
  • High Rise Aluminum Intake Manifold
  • HEI Distributor
  • NGK Spark Plugs
  • Moroso Mag-tune sleeved, under-header wire kit (terminals installed)
  • 8″ Harmonic Balancer
  • Oil Pump, Pick-up and 8-Quart Oil Pan
  • Front Timing Cover
  • IMCA-issued seals professionally installed
  • Dyno Sheet of your Engine

Important Notes

  • Requires the addition of a carburetor, starter and water pump (not included).
  • Requires an externally balanced flywheel (not included).
  • The 8-quart Circle Track oil pan is 7 inches deep at the sump. It will clear most GM rear-steer chassis with the stock engine location.
  • For Circle Track Racing only – not intended for street use.
  • Broken-in, dyno-verified HP/TQ, and IMCA-sealed for competition. Includes distributor (installed and timed) and fitted spark plug wires.
  • This item is made to order. It will be shipped from our warehouse when it is produced.
