How to Convert a 350 Into a 383 Stroker
- Purchase and install a 383 stroker crankshaft, rod and 10.5-to-1 piston set.
- Install a set of four-bolt steel main caps over the center two crankshaft mains if you’re using a two-bolt-main block.
- Install a set of ported L31 Vortec cylinder heads.

Can I turn my 350 into a 383 stroker?
The length of stroke in a 350 is 3.48, and it uses 350 cubic inches of the engine. After the transformation, the 383 stroker gets a longer stroke, and the engine displacement increases without bringing any change to the block’s size. The displacement rises from 350 cubic inches to 383 cubic inches.
How much do you bore a 350 to make a 383?
And at a glance, building the 383 seems almost as simple as mashing a toasted marshmallow and a piece of chocolate between a couple of graham crackers. 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.
Are 350 and 383 blocks the same?
A 383 is a 350 block bored 0.030″, with a 3.750″ crank (same stroke as a 400) instead of the 350’s 3.480″ stroke. It is a common combination, and if equipped with a good cam and heads, will make more horsepower and torque than a similarly built 350 (355 with the 0.030″ overbore).
How much HP does a 383 stroker have?
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 makes a 383 small-block Chevy?
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 size is a 383 stroker?
Displacement Calculation
The 383 stroker engine has a bore of 4.03 inches and a stroke of 3.75 inches versus the GM 350’s bore of 4.00 inches and 3.48 inches of stroke.
Does boring an engine increase horsepower?
From a performance standpoint, boring an engine could give you more horsepower and torque, as it will change the engine’s displacement.In general, the greater your engine’s displacement, the more power it can create. Lower displacement may result in greater fuel economy.
What size block is a 383 stroker?
3.800-inch
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.
Can you supercharge 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 boost can a 383 stroker handle?
11. The crank pulley was combined with a 3.25-inch blower pulley to produce a maximum boost pressure of 9.6 psi on our BluePrint 383.
Whats better 383 stroker or 350?
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’s better than a 383 stroker?
The 427/434 will accelerate most medium to heavy cars dramatically quicker than the common 383’s on the market. The main difference between a 427/434 and the 383 is that the 427/434 torque comes in much lower.This engine will accelerate a 3600 lb or heavier car much better than the 350 or 383.
What does Stroker car 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.
Who invented the 383 stroker engine?
Joe Sherman
Joe Sherman: 383 Chevy and Low-Buck Engine Pioneer Passes On.
What size carburetor do I need for a 383 stroker?
Carburetor For 383 Stroker
recommends a 650 cfm carburetor. A 750 cfm carburetor will make the engine more powerful, but it is the largest that should be used unless the engine is being used for racing.
Did Chevy make a 427 small block?
Chevrolet’s 427 cubic-inch big-block didn’t last long, but it made an indelible mark in the performance world. The Mark IV big-block 427, available only from 1966–69, is the one that muscle car fans perhaps most revere.
What is a 408 stroker?
Our 408 Stroker Crate Engine is built with a 350 block and a 4-inch stroker crank.A 350 Chevy with the same block clearance as a 383 and a standard base circle cam houses a big block stroke and 6-inch rod. The torque in this thing will give you goosebumps!
Why is it called a 383 stroker?
Chevy does recommend that this engine be paired with a Holley 4-barrell carburetor to ensure that the maximum performance specifications are reached. 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.
What are the benefits of a stroker motor?
A stroker kit increases an engine’s displacement by lengthening the stroke of the piston. In a kit will be bespoke engine components altered from OEM parts to achieve this increase in stroke. They allow the piston to travel further up and down the cylinder thanks to the use of a different crankshaft.
