BluePrint Engines BP4967CTFDK GM 496 Stroker 600HP EFI Fully Dressed Engine

Description

Modern electronic fuel injection anchors the BluePrint BP4967CTFDK GM 496 EFI Engine. This 8.1L 496ci big block Chevy stroker V8 delivers 600HP for severe duty commercial long block repower chassis conversions. Master technicians must plumb an unrestricted 3/8in fuel return line back to the fuel tank because high volume electric EFI pumps trigger erratic rail pressure spikes on deadhead lines.

Heavy duty ASTM Class 35 gray iron forms the four-bolt main tall deck case on this BluePrint engine assembly. A forged 4340 chromoly steel 4.250in stroker crankshaft spins inside micro honed bearing saddles to withstand severe combustion pressure spikes. Cranking pulls 195A across 12V starter circuits. Dry mass totals 695 lbs inside an installation envelope of 32in length by 29in width by 31in height holding 8.0 quarts oil capacity.

Key Features of BluePrint BP4967CTFDK

Fleet operators buy BluePrint BP4967CTFDK GM 496 EFI Engine setups to conquer extreme route terrain during an industrial engine rebuild. BluePrint high flow aluminum cylinder heads feature rectangular intake runners and 119cc combustion chambers optimized for pump gas.

• Massive 496ci displacement delivers monumental torque multiplication across low engine speeds.
• Four-bolt main bearing journals secure the lower end against high dynamic stress.
• Self tuning throttle body EFI system calculates instant air-fuel adjustments across wide load ranges.
• Forged steel connecting rods handle extreme reciprocating loads under persistent throttle.
• The BP4967CTFDK dressed engine incorporates forged pistons with low friction skirt coatings.
• Complete front accessory serpentine drive system drives the alternator, water pump, and power steering pump.
• Multi layer steel cylinder head gaskets maintain reliable fire ring seals against block decks.

Dyno Verification Shop Limits

Factory dyno testing subjects the BP4967CTFDK commercial core to controlled continuous absorption sweeps. Dynamometer readouts record 600 continuous BHP and 575 ft-lbs torque output at 4,800 RPM. Main oil gallery pressure maintains 62 PSI at 195°F operating temperature. Exhaust gas temperature stays below 1,420°F under continuous rated output runs. Cylinder compression verifies at 185 PSI per bore with under 3% variance and crank runout within 0.0003in TIR.

Shop Deployment Field Upkeep

Electronic throttle linkages respond smoothly to 4.5 lbs applied cable tension across full quadrant sweep. Do not install this massive big block powertrain into utility vehicle frames lacking heavy duty front coil springs rated above 4,200 lbs front gross axle weight.

• Replace motor oil and install new heavy duty spin-on filter canisters every 3,000 miles.
• Inspect hydraulic roller lifter action and rocker arm lash every 25,000 operating miles.
• Check cylinder head bolt torque to 110 ft-lbs following initial thermal break in cycles.
