Info

The SP350/357 is based on a tough, Chevy four-bolt block that holds a strong nodular iron crankshaft, good rods, and aluminum pistons. The high-lift camshaft gives the engine its own unique, aggressive idle. The cam is based on the same one found in 1965-67 Corvette 327 engines, but it has even more lift and duration.

Chevrolet Performance SP350 357HP Turnkey Engine Includes:

  • Fully GM assembled long block
  • Black Steel Valve Covers with Chevy Bowtie Logo
  • Black 14" Air Cleaner
  • Oil pump, pick-up and oil pan
  • Aluminum Performance Intake
  • Holley 670CFM Carb
  • HEI Distributor, Plug Wires, Looms and Plugs
  • 12-3/4” Auto Trans Flexplate
  • 8” Harmonic Balancer
  • Front timing cover
  • Oil Filter and Adapter
  • Passenger Side RH Oil Dipstick and Tube

Note: This engine is shipped dry and requires oil system to be primed and valvetrain adjusted prior to initial start up. Harmonic balancer used will need to be checked for exact TDC (top dead center) location and timing pointer modified/adjusted to correct location.
