The 318 in your Duster is a small block. On Chrysler engines, it's easy to determine a small or big block engine not only by the size, but the location of the distributor. On a small block, it's in the back behind the carb. On a big block Chrysler, the distributor is located on the front of the engine, diagonally installed from the passenger side of the block. I owned many small block and big block Chrysler products over the years including 3 Chargers, 2 Road Runners, a Fury, Monaco, Aspen R/T and a Sebring. Chevrolet engines are a little more difficult to determine the small block/big block status. Other that the fact of the huge valve covers on a 454, you'll have to rely on the engine numbers or the tag on the firewall and decode the numbers on the plate.

a 318 is a small block. A "big block" Is bigger! You can see the difference in the size of the engine. 396, 409. 454 are "big blocks" There was a small block 400.

In general most engines 350 c.i. and under are "small Block" , and Engines over 350.c.i. and considered "Big Block" engines, there are lots of details and exceptions , but this is a good rule of thumb
The 318 in your Duster is a small block..but with the right parts and tuning will easily eat any import "Tuner "car on the street today.
Small block engines tend to be smaller displacement and are designed to make their peak horsepower at higher rpm Big block engines have displacement on their side and make peak power at lower rpm. Most early trucks came equipped with larger engines so they could move heavier loads from idle more easily.
Low rpm power is commonly referred to as "Torque".

the difference is the displacement or size of engine true most have larger #s like 383&426 but thay did make a big block 318 but I think they were mostly used in trucks or special orders. If you can find you engine code usally on the front of the engine you can find out for sure.

Most 350s and below are small block. Ford confused things by making two different 351s. The big block Cleveland and small block Windsor.
