(versus the 350's 3.480-inch stroke) equals 383 cubic inches.

Can you turn a 350 into a 383 stroker?

The biggest advantage to putting a crankshaft from a Chevy 400 into a 350 block to produce 383 cubic inches is that more displacement equals more power. Also, the longer crank throw produces more downward thrust, which translates into torque. And torque is what we're after, especially in a truck.

What size engine is a 350 bored 30 over?

030 over it usually means it's been rebuilt once, but not always. It also adds cubic inches to the displacement, a 350 bored . 030 over is 355 CI.

How much can you bore over a 350?

What block is used for a 383 stroker?

The GM small block 5.7-liter 350 is the base for the 383 stroker; the 350 crankshaft is exchanged for a GM small block 400 crankshaft. The 400 crankshaft rod journals produce a longer stroke for the engine and create a larger displacement.

What's the difference between 350 and 383 engine?

Rather, a 383 is about 28 cubic inches larger than a typical / comparable restored 350 which is actually 355 square inches in width. The cubic incher with the height of “030” over 350 actually has a fuel capacity of 355 pounds per square inch. We get 355 hp per cubic inch for a build of a mild size.

Is a big block better than a small block?

Big block engines are larger in size and weigh more, but they produce more consistent power and torque to overcome the weight. Small block engines are smaller for better acceleration and handling, but more recently built models can be just as powerful as big block engines.

Is a 383 A big block?

The 383 Chrysler B engine is known as the Mopar big block that nobody loves. Typically, gearheads favor its beefier big brother, the 440. The 383 B is characterized by its large cylinder bore of 4.25 inches with a short stroke of 3.375. (That is in comparison to the 440's 3.75.)

How do you clearance a block for a stroker crank?

The minimum acceptable clearance is 0.060 – 0.080-inch between all moving parts and the block. You can check this with a feeler gauge or welding rod of the appropriate thickness.
