What engine is in a viper?

Answer 1

ALthough the block was essentially an LA small block engine with tweo extra cylinders, the prototype blocks were cast by Lamborghini, at the time a Chrysler division. Some felt that the pushrod two-valve design, while adequate for the truck application for which the engine was originally created, was unsuitable for a performance car. However, Chrysler was uncertain about the Viper's production costs and sales potential and so declined to provide the budget for the modification.

The Viper V10 is an 8.4-liter aluminum engine that produces a ground-shaking 600 horsepower and tire-smoking 560 lb.-ft. of torque.

It features a deep-skirted V10 aluminum engine block, cylinder heads equipped with Computer Numerically Controlled (CNC)-shaped combustion chambers, large valves and Variable Valve Timing (VVT). VVT electronically adjusts when the exhaust valves are open and closed according to engine speed and load, allowing the engine to "breathe" cleaner and more efficiently.

The two-piece intake manifold combines cast aluminum

lower with smooth runners for better air flow, bolted to a die-cast aluminum upper plenum.

A revised air-cleaner box with a low-restriction filter sends air through a dual electronic throttle control into the intake module.

The air-fuel mixture in the cylinders is ignited by platinum-tip spark plugs fired by individual plug coils mounted on the cylinder-head covers.

Within the cylinders, pistons are equipped with large-diameter floating pins with bronze bushings for high-load capability.

Forged powder-metal connecting rods are secured with aircraft-quality fasteners for increased fatigue strength.

Engine lubrication is managed by the large oil pump and a swinging oil pickup adapted from Viper competition engines, to ensure proper oil pressure in high-rpm and hard cornering conditions.

The Tremec T56 six-speed (model TR6060) conveys power via a GKN ViscoLok speed-sensing limited-slip differential.
