Built from all new parts – not remanufactured – this high output classic Chevy 350 is the perfect long block for an engine builder on a budget. With a reliable 333 hp and 381lb.ft. of twist, the Karl Kustoms 350 HO crate engine is the undisputed champ for getting the most bang for your buck. But budget doesn’t mean cheap, this time-tested motor comes with:

  • Chevy four-bolt block with a strong nodular iron crankshaft and aluminum pistons
  • High-lift camshaft based on the Corvette 327 engine for a distinctive and aggressive idle
  • Iron Vortec heads fitted with 1.94/1.50-inch valves
  • Chrome valve covers

The 350 HO makes its peak 381 lb.-ft. of torque at a very usable 3,800 rpm and it pairs well with any number of transmissions you can throw at it, like the SuperMatic 4L75-E Four Speed.

What’s Included

  • Fully GM assembled long block
  • Chrome Steel Valve Cover with Chevy Bowtie Logo
  • Oil pump, pick-up, and oil pan
  • Front timing cover
  • Passenger Side RH Oil Dipstick and Tube

Important Information
