What is a 383 stroker Chevy engine?

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.

What is the average horsepower 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 are the benefits 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.

What is a 383 stroker Chevy?

Big torque 383 stroker

When it comes to cranking serious torque from the classic Small-Block, it's hard to beat the 383 stroker combination, which uses a long, 3.800-inch stroke with 4.005-inch bores to generate exceptional low-end pulling power and surprising high-rpm horsepower.

How many MPG does a 383 stroker get?

I've got a 383 Stroker (10:1 with Dart heads) in my 66 with a properly tuned 650 Holley vacuum secondary carb and MSD Pro Billet ign system. I'm getting an average of 9/10 mpg on 93 non ethanol gas. I don't "punch" the car often and most cruising down the road is done at 3-35K.

Step-By-Step Instructions To Getting 450 Horsepower Out Of A 383 Stroker - Trucks! S1, E16

What does stroker engine mean?

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.

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.)

What size block is a 383 stroker?

A 383 stroker has a 0.030 over bore of the stock 350, giving you 4.030 as a bore diameter.

How much is a Chevy 383 stroker?

The HP94 Chevy 383ci stroker from ATK is being offered by Jegs at the low price of $3,993.99, but is found throughout a range of big-box stores, so it might pay to shop around some, as is the case with any large-volume crate engine commodity like a Chevy 383ci stroker.

What are the disadvantages of a stroker engine?

Stroker is a lot more torque but more expensive components needed to make sure your motor can handle the higher piston speed and stress on the big ends of the con rod.

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.

Does a stroker motor rev higher?

Stroker kits result in more torque in the low rev range, but the engine's ability to reach high revs will be hindered due to the increased travel in the piston's movement, meaning a stroker kit can decrease the responsiveness of an engine.

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.

How much horsepower does a 454 stroker engine have?

The 454 EFI version was rated from 230 hp (172 kW) to 255 hp (190 kW) and from 385 lb⋅ft (522 N⋅m) to 405 lb⋅ft (549 N⋅m) of torque.

Do you have to bore a 350 to make a 383?

A 0.030-over 350 block, plus the 3.750-inch stroke from a 400 small-block (versus the 350's 3.480-inch stroke) equals 383 cubic inches.

Why is it called 383 stroker?

As you might guess from the name, the displacement of this engine is 383 cubic inches (6.27L), thanks to the longer stroke provided by the Chevy 400 crankshaft. This engine has a bore of 4 inches with a stroke of 3.8 inches.

Who invented the 383 stroker motor?

The 383 small-block we all know and love today? Thank Joe. As far as it's known, he fathered the 383 back in the late 1970s, and it would go on to become an overwhelmingly popular combination: stuff a factory 400ci 3.75-inch-stroke small-block crank into a notched-for-clearance 0.030-over 350.

Is a 383 and a 440 the same block?

The major difference between these two Mopar legends is the deck height of the block: 9.98-inch for the 383 and 10.725-inch for the 440.

Was a 383 a Hemi?

The Chrysler-owned 383-cubic-inch V-8 Dodge and Plymouth engine was a high-performance powerplant that played a role in the muscle car era of the 1960s and early 1970s before the 426 Hemi rendered it obsolete.

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

The affordable and underrated 383 gets a huge boost in the arm by Muscle Motors—to the tune of 559 hp and 611 lb-ft.

What makes more power bore or stroke?

The short answer is that a bigger bore is generally the best way to get more power. It creates more space, allowing for bigger valve openings, which in turn can bring more fuel and air into the cylinder.

Does boring out an engine increase horsepower?

Boring an engine involves using machines to widen and taper the cylinders. From a performance standpoint, boring an engine could give you more horsepower and torque, as it will change the engine's displacement.
