What crank is used in 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. Professional machining of the engine is required.
How much HP can a 383 stroker handle?
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.
How do you turn a 350 into a 383 stroker?
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.
What’s the difference between a 383 and a 383 stroker?
The stroker has an increased piston speed because of the longer stroke. The rod and piston have to travel in a larger diameter in the same engine rpm. This increases the piston speed, which makes the stroker pull more air at a lower engine rpm. A 383 has the same piston speed at 2,500 rpm that a 350 has at 3,100 rpm.
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.
Can a 383 stroker make 500 hp?
That combo would probably make around 465 hp and nearly 500 lb-ft, but at less rpm. But never mind that….Hot Rod’s Proven Recipe For A Simple Chevy 383 That Knocks Down 500 HP And 500 LB-FT.

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 do you tell if I have 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.
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’s the biggest cam for a stock 350?
COMP Cams CL12-600-4 is the biggest cam for stock 350 and plays its role as the topper since 1976.
Is 350 or 383 better?
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.
