Value Power Valvetrain Dynamic Timing

Dyno testing validates 375 brake horsepower at 5200 RPM and 460 lb-ft torque at 3600 RPM across a broad 1500 to 5400 RPM operating range. The flat tappet cam features 214 degrees intake and 224 degrees exhaust duration at 0.050 inch lift, with 0.470 inch intake and 0.470 inch exhaust lift. The motor pulls 16 in-Hg vacuum at 750 RPM on 87 octane fuel, holding 45 to 60 PSI hot oil pressure.

TorqueFlite Transmission Chassis Envelope Spacing

Standard Chrysler small block exterior dimensions drop straight into Dodge and Plymouth passenger car engine compartments. The crankshaft requires an external balance torque converter or flywheel matched to standard Chrysler A727 or A904 transmission bellhousings. Exhaust ports align with factory manifolds or aftermarket headers, while the front sump pan clears steering linkages.

Flat Tappet Run In Restrictions

Technicians must pre prime the oil galleries using high zinc break in oil and run the motor at 2000 RPM for twenty minutes to establish flat tappet camshaft wear patterns. This cruiser package is not built for supercharger boost, solid roller RPM limits above 5400 RPM, or uncalibrated nitrous kits.

• Drain break in lubricants and replace the spin on oil filter after the first 500 operating miles.
• Perform regular motor oil changes every 3000 miles or six months with high zinc petroleum oil.
• Inspect valve lash adjustments and check spark plug deposits every 6000 street miles.
