Vortec 5700 Dyno Output Profile

Dynamometer testing confirms 255 brake horsepower at 4600 RPM and 330 lb-ft torque at 2800 RPM across an operating band between 1000 and 5000 RPM. Cam duration measures 191 degrees intake and 196 degrees exhaust at 0.050 inch lift, producing 0.414 inch and 0.428 inch valve lift. The motor creates 18 in-Hg manifold vacuum at 650 RPM on 87 octane fuel, while the oil pump delivers 40 to 55 PSI hot pressure.

Truck Subframe Spacing Transmission Alignment

Standard small block Chevrolet dimensions drop straight into GMT400 pickups, Tahoes, and commercial chassis cabs without modifications. The traditional GM V8 bellhousing pattern bolts straight to 4L60E and 4L80E automatic transmissions. Exhaust manifold ports match original downpipes, maintaining clearance around intermediate steering shafts and front suspension torsion bars.

Roller Valvetrain Break In Rules

Pre prime the engine oiling channels with high zinc break in oil using an oil pump drive tool prior to startup. This replacement truck engine is not engineered for marine bilge setups, forced induction boost exceeding six PSI on stock ring end gaps, or unmetered nitrous oxide systems.

• Drain break in oil and replace the spin on lube filter after the first 500 operating miles.
• Perform regular motor oil changes every 3000 miles or six months with high zinc synthetic oil.
• Inspect ignition distributor rotor wear and check fuel injection pressure every 6000 road miles.

Factory Build Sheet Crate Verification

Protection includes a 2-Year / 24,000-Mile factory limited warranty guarding against defective components. The shipment crate contains the assembled long block, cast iron cylinder heads, pushrods, rocker arms, installation guide, and official factory build certification paperwork.
