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 do you need to install a stroker kit?
Do You Know How To Install Your Stroker Kit?
- Clean and prepare the crank block.
- You should ensure that you clean the engine block carefully together with all the components so as to ensure that the bearing placement does not have any complications.
- Inspect the NIP and back contact.
- Inspect oil clearance.
- Main bearing alignment.
- Cylinder bore/ rod beam installation.
What is the advantage of a stroker engine?
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.
How much horsepower does a 383 stroker engine have?
That combo would probably make around 465 hp and nearly 500 lb-ft, but at less rpm. But never mind that. The point here is 502 lb-ft at 4,700 rpm and 500-plus horsepower from 5,700-6,200 rpm.

Who makes the best 383 Stroker engine?
3. Blueprint SBC 383 Stroker Crate Engine Base Model. Crafted with new BluPrint cast steel crankshaft, the SBC 383 Stroker Crate Engine Base Model is among the best 383 crate engines in the market. With a compression ratio of 10:1, you can expect high performance for years.
Are stroker engines reliable?
A few years ago stroker motors weren’t very reliable but with testing and redesigning now they are almost as reliable as a stock motor as long as you treat them right.
How long do stroker motors last?
With good quality parts that are compatible with one another combined with good machine shop work, careful assembly, and proper break-in, a stroker should last well over 100k miles.
How many MPG does a 383 stroker get?
Around-town gas mileage is about 14 – 16.
Is a 396 a good engine?
The 396 is a good revving engine, so you’d want to run a steel crank so it would live at the rpm you’d have to run it to make HP. And probably a roller cam, as flat tappet cams in big blocks have a nasty habit of “going away” relatively easily.
How much HP can a 396 make?
The 396 was offered in several configurations and produced different horsepower and torque ratings, depending on its intended application. The 396 with a 10.25 compression ratio produced 325 horsepower at 4,800 rpm and 410 ft. lbs. of torque at 3,200 rpm.
How much HP can a 396 handle?
A 396 with a forged crank/rod/piston will take 300-400 shots easy.
What is the difference between a 396 and a 427?
The cranks have the same stroke 3.76. The 396 crank is lighter having 3/4″ wide 3rd counterweight. The 427 cranks look identical except the 3rd counterweight is 7/8″ thick, heavier crank due to heavier pistons for the larger bore.
Can a 396 be stroked?
It’s no secret 396/402 blocks can be safely bored to 427/454 size of 4.251 inches (. 060 over). Bore sizes larger than this in any of these blocks can be accomplished – at your own risk (added with emphasis).
Can you put 454 heads on a 396?
For example, tossing a set of 454 open-chamber heads on a 396 could radically reduce the compression ratio because of the roughly 10cc larger chamber on a short-stroke engine.
How far can 396 be bored?
With a bore spacing of 4.84 inches and a potential maximum safe bore size of 4.625 inches (theoretically, for the big-block design-most 396 blocks can only be bored out to 4.250 inches), the 396’s 4.094-inch bore diameter is laughably small.
Are 396 and 454 blocks the same?
The blocks are the same with the exception of the bore of the cylinder when the cast was made. The walls will not allow for that much bore. If you wish to use the 454 crank and rods with the 396 block you can purchase a set of pistos with the corrocponding compression hieght and have a stroker 421 CI engine.
What is the difference between a 396 and 402?
Although it displaced 6-cubic-inches more than the 396 and had a bore that was 0.03 inches wider than the 396, Chevrolet marketed the 402 as a 396 on its smaller cars like the Nova, while labeling it as a 402 in its full-size automobiles.
