Vortec Powerband Dyno Calibration

Engine dyno records confirm this V8 outputs 315 brake horsepower at 5200 RPM alongside 338 lb-ft torque at 4400 RPM across an operating band from idle to 5600 RPM. Camshaft duration measures 196 degrees intake and 201 degrees exhaust at 0.050 inch lift, producing 0.481 inch intake and 0.481 inch exhaust lift. The combustion chambers draw 17 in-Hg vacuum on regular 87 octane unleaded fuel, holding 40 to 55 PSI hot oil pressure.

Frame Mount Spacing Bellhousing Alignment

Factory small block GM dimensions drop straight onto original rubber or polyurethane motor mount perches in GM trucks and sport utility chassis. The bellhousing mounting flange matches standard GM automatic or manual transmissions with zero spacer plates. Exhaust manifold ports match original downpipe alignments, clearing front suspension crossmembers and steering linkages.

Crankcase Lubrication Pre Lube Regimen

Technicians must pre prime internal oil galleries using high zinc break in oil via a priming tank connected to the oil gallery plug prior to startup. This replacement V8 long block is not designed for supercharger boost, unmetered nitrous oxide injection, or competition track racing.

• Drain break in lubricants and replace the spin on filter after the first 500 accumulated road miles.
• Change crankcase motor oil every 3000 miles or six months using manufacturer approved engine oil.
• Inspect accessory belt tension and examine spark plug deposits every 6000 street miles.

Manufacturer Warranty Physical Crate Manifest

Protection includes a 2-Year / 24,000-Mile factory limited warranty backing internal parts against defect. The delivery crate contains the remanufactured long block, aluminum cylinder heads, pushrods, rocker arms, comprehensive installation instructions, and factory warranty registration paperwork.
