The balanced rotating assembly (typically includes crankshaft, pistons, rings, connecting rods, rod bearings, and balancer) featured in this engine:

• 4.000" stroke nodular iron crank
• 6.580" rods with ARP rod bolts
• 9½ to 1 compression pistons

More special features of this engine include:

• Seasoned block that has been vatted, magnafluxed for cracks, thermal cleaned and steelabrated, bored, honed and plateau honed to fit new oversized pistons
• Deck head gasket surface on block to ensure a good long lasting seal
• New CompCams Split-duration hydraulic cam
• Installed on this engine is the famous Australian 2V closed chamber heads. They are casting #ARDIAE and have the "closed chamber" design of the early 4 barrel Cleveland heads but with the 2 barrel port sizes.
• Heads have been vatted, glassbeaded/steelabrated and magnafluxed for cracks
• 3-angle valve job
• Both heads resurfaced
• 60cc "quench" chambers vs the American 75cc open chamber head
• These heads have been used in the place of the American heads to increase compression and maintain low-end performance and boost all-around power
• Will work with stock exhaust manifolds
• Deck surface cast thicker than American heads
• New Valve guides
• Assembled with all New 2.040"Int/1.660"Exh valves
• New High performance valve springs setup to be used with CompCam's split-duration cam
• New Oversize pistons and rings
• New Heavy duty double row timing set
• New High volume oil pump
• New Brass expansion plugs
• New Oversize main and rod bearings to fit reground 4.00" stroke crankshaft
• New Edelbrock Performer aluminum intake manifold
• This engine comes with a 2" high intake to carb spacer to increase plenum volume. This spacer increases the carb-to-plenum floor distance which atomizes the fuel better and also enhances low-rpm torque and throttle response. This engine takes a square bore carb. This engine works best with a 750cfm Holley carb (not included) and a 2400 rpm stall speed converter if being used with a automatic transmission
• All parts are painted separately before assembly for that show quality look

This engine comes completely assembled with oil pan, timing cover, harmonic balancer, valve covers, and Edelbrock Performer aluminum intake manifold.
