    Blueprint Engines Short Block Assemblies are a great basis for a drivable and reliable high performance engine. All rotating assemblies are balanced within 2 grams on a computerized balancer.

  • Cast Iron Crankshaft
  • Cylinder wall thickness ''sonic tested''
  • Cylinders bore angle corrected to be 90° perpendicular to crank centerline
  • Cylinder bore centerline corrected to be exactly centered over crank centerline
  • Decks machined parallel to crank centerline
  • Right and left side decks machined equal distance from crank centerline
  • Main bearing bores align honed to correct size and straightness
  • Cylinders computer honed to tolerance of 200 millionths of an inch
  • Cylinders plateau finished for virtually instant break-in
  • Screw-in oil galley plugs installed in place of soft plugs

  • What oil pan works with this sb, harmonic balancer, flywheel (not flexplate), timing cover.?? Cost?

    Asked by: OLDcg
    This engine is based off of the early style Chevy 350 with a two piece rear main seal. The oil pan the you do use on your build will need to fit your chassis and the stroke of our crank. Balancer that will be required is externally weighted for a 400 cubic inch engine. Flywheel can be internally balanced and you will need to use the balance plate that we ship along with the engine.

    I have a flat tapper camshaft in a 72 350 will it work with this block?

    Asked by: Bowtie69
    The block that we use on this engine build is the early style two piece rear main seal block, both a flat tappet and a roller camshaft would work on this engine.

    I have 1969 302 out of a Z/28 that I lost an oil ring and I wanted to use all of the parts from that engine on a new short block. Will this 383 work with the old camel hump heads, roller rockers, etc. from that engine?

    Asked by: markinnaples
    Yes, those parts will work on this engine.
