    4. AISI/ASTM A681 D2 Grade Steel Forging

    Heating for forging of AISI D2 tool steel should
    be done slowly and uniformly. Soak through at 1850°-1950°F and reheat as often
    as necessary, stopping work when the temperature drops below 1700°F(926℃). After D2
    die steel forging, cool slowly in lime, mica, dry ashes or furnace. AISI D2 steel
    should always be annealed after forging.

    5. D2 Tool Steel Heat Treatment

    • Heat Treatment

    ASTM  D2 steels alloy should be preheated very slowly to 815oC (1500oF) and  then temperature can be increased to 1010oC (1850oF). They are then held  at 1010oC (1850oF) for 20 to 45 minutes and air cooled (air quenched).

    • Annealing

    Annealing  of D2 tool steels material should be done at 871 to 898oC (1600 to  1650oF) followed by slow furnace cooling at 4.4oC (40oF) per hour or  less.after which cooling rate may be increased. Suitable precautions  must be taken to prevent excessive carburization or decarburization.

    • Stress Relieving

    When  desirable to relieve the strains of machining, heat D2 grade steel  slowly to 1050°-1250°F, allow to equalize, and then cool in still air  (Strain Relieving).

    • Preheat Prior To Hardening

    Preheat slowly to 1350°-1450°F and hold at this temperature until grade steel D2 material is uniformly heated.

    • Hardening

    After  thorough preheating, heat to 1800°-1850°F. Hold the work piece at the  hardening temperature until it is completely and uniformly heated.

    • Quenching

    AISI  D2 steel tool material is an air hardening steel and will develop  hardness on cooling in still air. To avoid scaling and prevent  decarburization of the work piece surface, controlled atmosphere or  vacuum furnaces are recommended. If these furnaces are not available,  pack hardening, salt baths or wrapping the piece in stainless steel foil  will provide some degree of surface protection in the hardening  process. Parts should be allowed to cool to 150F, or to where they can  be held in the bare hand, and then temper immediately.

    • Tempering

    The  tempering temperature on material D2 steel may be varied according to  the desired hardness. D2 steels can be tempered at 204oC (400oF) for  achieving Rockwell C hardness of 61 and at 537oC (1000oF) for a Rockwell  C hardness of 54.

    6. D2 Tool Steel Material Application
     AISI grade D2 tool steels are used for long run tooling applications,  where wear resistance is important, such as blanking or forming dies and  thread rolling dies.

    Some main applications for D2 tool steel are as below:

    Blanking  Dies, Forming Dies, Coining Dies, Slitting Cutters, Heading Tools, Long  Punches, Forming Rolls, Edging Rolls, Master Tools, Beading Rolls,  Intricate Punches, Extrusion Dies, Drawing Dies, Lamination Dies, Thread  Rolling Dies, Shear Blades, Burnishing Tools, Gauges, Knurls, Wear  Parts.

    Before the nova was painted (black) and restored

    383 Stroker: (633hp/577tq @ fly)
    1969 Original SS 350 Block – 4 bolt main (3970010 cast numbers)
    - block had been resin filled for strength

    Eagle – 4340 Forged 3.75″ crank (this is an actual 383 specific crank, not a 400 crank milled down to a 383)
    -Knife Edged and Lightened

    Eagle H-Beam 4340 Forged Rods (6″ rods)

    JE 4340 Forged Pancake Pistons (full floating pins and nitrous reliefs) (11:1 Compression = Runs just fine on 91 octane pump gas, but loves 103 octane)
    - Pistons were Ceramic Coated for Nitrous but nitours has never been run on it. (been wanting to but never got around to it)

    64cc Edelbrock Performer RPM Heads (Aluminum)
    -Fully ported and port matched to the intake and exhaust
    -Valves Sizes increased from 2.02/1.60 to 2.08/1.60
    -Rev Kit / K-Motion Springs
    -Comp Full Roller Rockers

    Holley Strip Dominator Intake Manifold
    -Port-matched to heads

    Holley 830cfm Mechanical Double Pumper Carb (re-jetted with jet kit included)
    -fuel pump is mounted right next to the Fuel Cell and is fully plummed with dash 8 AN fittings and dash 8 steel braded fuel lines.
    All Transmission lines are done the same way as well

    Iski Cam – Solid Roller Cam – .602/.602 lift 300/300 duration with 1.6′ rockers = .642 final lift

    Ignition:
    MSD 6AL Box with changeable rev limiter chips
    MSD Distributor

    Griffin 2 – 1 inch core radiator
    Black Magic Electric Fan

    Entire assembly has been blueprinted, matched and balanced to each corresponding part.

    Exhaust:
    Hooker Supercomp Headers
    Dual 3″ Tubes
    Dual 2 Chamber 50 Series Flowmasters (this setup sucks… get the Borla XR1s instead)

    Drivetrain:
    TH 350 Manual Valvebody Race Transmission
    Beefed up Driveshaft by Whittier Driveline
    3.73 gears with a mini spool in video, then switched to 4.56 minispool, but that was too much, now its got a 12bolt posi 4.11
    Heat treated axles
    Rear-End was a 10-bolt (sucks..) now 12 bolt.
    Multi leaf springs and lift bars
    4000 Stall with anti balloon plates for nitrous
