So I finally got to work on getting my motor back to running condition( keep finding more and more things damaged, broken, or leaking.) and seeing how both motor mounts were broken even though I thought the right one was seemingly impossible to break...I decided it would be a great time to find out about the statistics of the motor. looking at the casting number i found out information i was misinformed on

what i was told was it was a 1990 318 (higher performance) police roller cam motor.
so far I found out it was made on 10-25-84.
it is a roller motor it has the 432 3330 318 code.

i would love to know the HP/Torque rating of this year and if anyone can verify if this is the so called "higher" performance block I was told. I just want to know out of curiosity.
 
1984-1989 318 2 bbl carb 120hp @ 3600rpm Torque 245 @ 2000rpm
318 4 bbl carb 155hp @ 4000rpm Torque 240 @ 2000rpm

This is just the normal 318 but I'll keep looking.
 
I know it's not what your looking for but just so you know...... S in the Vin# would mean 318-4 Police 1983-89
 
CARBS:
Four-barrel Carter Thermo-Quad and Rochester Quadrajet carburetors were used in police applications starting in 1978. The 318 received roller lifters and a fast-burn cylinder head in 1985.
HEADS:
1975-’84
The original heads were replaced by a casting that had big, elongated pads with room for an AIR (smog pump) hole under each exhaust port. Some were drilled for AIR, others were blank (they can be converted). The common castings are 3769973, 4027163 and 4027593.....................Just for the record, the 360 heads were used for the 318 police car engines starting in 1980.

S" In the VIN #: This indicates the heavy duty 4bbl 318.

Engine: The engine should be a 318 with 360 heads, four barrel intake manifold, heavy duty exhaust manifolds, double roller timing chain, hyperutectic pistons, special piston-to-block clearances (allowable by use of the hyperutectic pistons), heavy duty chrome plated oil rings, forged steel connecting rods, heavy duty valve springs, high strength rocker arms, high temp cylinder head cover gaskets, high temp valve seals and shields, lubrite treated camshaft (4bbl hydraulic version had 430/444 lift with 268/276 duration, roller version had 391/391 lift with 240/240 duration) , nimonic exhaust valves, special kolene cleaned cylinder heads, , , special silichrome-1 temp steel intake valves and a heavy duty water pump. (Specs from Dodge, Plymouth & Chrysler Police Cars 1979-1994 and the Allpar website).
