BluePrint PS5720CT Pro Series Chevy 572 745 HP Base LB

Description

Massive raw displacement defines the BluePrint PS5720CT Pro Series Chevy 572. This 9.4L 572ci big block Chevy stroker V8 generates 745HP for heavy industrial commercial long block repower skid integration. Master machinists must measure intake runner port height matching on customer-supplied manifolds because tall deck blocks use specific intake manifold spacers.

Solid ASTM A48 Class 35 gray iron lines the four-bolt main tall deck case on this BluePrint engine assembly. A forged 4340 chromoly steel 4.500in stroker crankshaft spins inside micro-honed bearing saddles to withstand severe combustion pressure spikes. Starter motors pull 195A on standard 12V circuits. Dry mass totals 650 lbs inside an installation envelope of 32in length by 28in width by 29in height holding 8.0 quarts oil.

Key Features of BluePrint PS5720CT

Shop owners buy BluePrint PS5720CT Pro Series Chevy 572 configurations to secure extreme cubic inches during an industrial engine rebuild. BluePrint high flow aluminum cylinder heads improve airflow velocity and thermal dispersion under heavy loads.

• Colossal 572ci displacement delivers monumental torque multiplication across low engine speeds.
• Four-bolt main bearing journals secure the lower end against high dynamic stress.
• Hardened steel valve seats resist unleaded fuel erosion over hundreds of operational hours.
• Hydraulic roller camshaft profiles deliver aggressive valve lift without sacrificing valvetrain life.
• The PS5720CT base long block includes forged pistons for superior strength under heat.
• Precision ground journals maintain 0.0016in oil clearances under continuous highway load cycles.
• Multi layer steel cylinder head gaskets maintain combustion seals against continuous cylinder pressures.

Dynamic Dyno Load Evaluation

Bench testing subjects the PS5720CT commercial core to full dynamometer absorption sweeps. The dynamometer records 745 continuous BHP with 680 ft-lbs shaft torque at 5,000 RPM. Hot gallery oil pressure maintains 62 PSI at 195°F operating temperature. Exhaust gas probes measure 1,420°F maximum temperature under sustained throttle. Cylinder compression delivers 190 PSI with under 3% variance and crank runout within 0.0003in TIR.

Field Service Boundary Requirements

Governor control linkages actuate smoothly against 5 lbs applied mechanical pull force. Do not install this tall deck base long block into truck engine compartments lacking vertical hood clearance for tall intake runner manifolds.

• Replace premium motor oil and heavy duty filter canisters every 3,000 miles or 120 run hours.
• Inspect hydraulic roller lifters and valve spring seat pressures every 25,000 operating miles.
• Verify cylinder head bolt torque to 115 ft-lbs following initial thermal break in cycles.

Commercial Warranty Delivery Manifest

Every long block carries BluePrint engineering backing for dependable performance across severe operations. Purchase includes a 30-Month or 50,000-mile limited replacement parts warranty. The wood crate package contains the assembled base long block, oil pan, timing cover, aluminum valve covers, internal oil pickup screen, and certified dynamometer inspection certificate.
