How do I know if my engine is a 383 stroker?

A 383 stroker is a 350 block with a 400 crankshaft. Check the casting numbers on the block to verify it to be a 350. Check the harmonic balancer as it is not solid but machined to to balance the rotating assembly. also the fly wheel or flex plate will have a larger weight on it than the other small blocks.

How do you tell the difference between a 350 and 383?

The only difference externally is the harmonic balancer. The 383 utilizes a stock 400 crank and balancer. The 400 harmonic balancer is larger and looks different than a 350 harmonic balancer.

What makes a motor a 383 stroker?

A 383 stroker has a 0.030 over bore of the stock 350, giving you 4.030 as a bore diameter. Putting the 400 crank in the 350 increases the stroke to 3.750. Other than that, all the other dimensions stay the same. If you do the math, you will get 382.6; round up and you have 383 ci.

Is a 400 small block better than a 350?

A small block 350 and a 400 have an identical block design. Most accessories will fit either engine. The major difference is found in the casting numbers and the way they are balanced. Most 350 cubic inch engines are internally balanced whereas the 400 engines are not.

How much horsepower can you get out of a 383 stroker?

The 383 stroker engines have been reported to achieve 330 horsepower with 410 foot-pounds of Torque, 395 horsepower with 410 foot-pounds of Torque and 395 horsepower with 410 foot-pounds of Torque.

What is the benefit of a stroker motor?

A stroker is an engine that has been modified to increase the length of the stroke and therefore has a greater engine capacity. Its benefits are improved torque and power.

Is a 383 stroker worth it?

Well-worth it for the added low-end torque, a mild 383 build is less than $200 more to put together than a 350. They’re so common now it seems hardly anyone builds up a 350 block without putting in a 3.75″ stroke crank.

How do you turn a 350 into a 383 stroker?

How to Convert a 350 Into a 383 Stroker

  2. Install a set of four-bolt steel main caps over the center two crankshaft mains if you’re using a two-bolt-main block. …
  3. Install a set of ported L31 Vortec cylinder heads.

Can you put a supercharger on a 383 stroker?

Add a Supercharger to a Well-built 383 and Get a Real Boost in Performance. Today it’s not uncommon to see superchargers finding their way onto just about anything short of a lawnmower. Blower companies offer bolt-on kits for virtually every application, be it an EFI-induced late-model or a carburetor-fed classic.

How much HP does a stroker kit add?

So, as a given rule, the more cubic inches an engine is, the more power it will make. However, the horsepower output will largely depend on the overall combination you are using. We could take a 500″ short block and with stock heads and a mild cam, it might make around 450-475 horsepower.

What cars came with a 383?

The 383 was introduced in 1959 to be placed in the Chrysler Windsor and the Saratoga while the luxury Chrysler New Yorker and 300 Series received the slightly larger 413-ci V-8. The initial 1959 383s were raised block V-8s with a 4.030-inch bore and 3.750-inch stroke and four-barrel carburetor.

Why do they call it a stroker motor?

As its name implies, a stroker is where we increase engine displacement by increasing piston stroke. When we increase stroke, we take the piston deeper in the cylinder bore, which increases displacement. The longer the stroke, the greater the fuel/air charge. … Remember, Ford stroked the 289 0.013 inch to achieve 302 ci.
