GENERAL INFORMATION
ENGINE IDENTIFICATION NUMBER OR CODE
The engine identification number is located on the
rear of the cylinder block just below the cylinder
head (Fig. 2). ENGINE: The 3.3L (201 Cubic. Inches.) and 3.8L
(231 Cubic. Inches.) displacement engines are 60É V
type six cylinder power plant with cast iron cylinder
block and aluminum cylinder heads (Fig. 1). Firing
order for these engines is 1-2-3-4-5-6. High turbu-
lence cylinder heads allow a 8.9-1 compression ratio. CRANKSHAFT: The nodular iron crankshaft is
supported by four main bearings, with number two being the thrust bearing. Crankshaft end sealing is
provided by front and rear rubber seal. PISTONS: The pistons are cast aluminum alloy.
Three rings are used. Piston pins, press fitted into
place, join the pistons to forged steel connecting rods. CAMSHAFT: The nodular iron camshaft is
mounted in four steel backed babbitt bearings. A
thrust plate located in front of the first bearing, and
bolted to the block, controls end play. Silent timing
chain drives the camshaft. This chain is enclosed by
a cast aluminum cover which also carries a front
crankshaft seal, provides front oil pan closure, water
pump mounting.
