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.
Why do stroker engines sound different?
The sound change would most likely be due to other parts of as package like headwork, different valves, camshafts, etc. If the only mod is the actual stroker stroker, there may be a tiny change in sound due to added displacement, but nothing radical or choppy.
Do stroker engines rev higher?
Torque is extremely important when it comes to low-end power which is where larger displacement engines will undoubtedly have the upper hand. Where shorter strokes would allow the engine to rev higher and faster (destroking), generating more horsepower, an increased stroke would increase the torque.
What are the disadvantages of a stroker engine?
Potential RPM range loss. Depending how nice the factory set was, you may loose top RPM range due to longer stroke. Possible decrease in engine life. Your rotating assembly may be stronger, but your block isn’t- you may possibly have more cylinder wear at higher output, however rod length may counter that.
Is a stroker engine 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 much HP does a stroker kit add?
A traditional 4.21/ 6.625/3.0 stroker kit ups the CID to 455 and raises the SCR to around 8.8-9.1:1- with the addition of a high-lift aftermarket cam, upgraded ignition, headers and a larger exhaust, an output of over 375-425 hp is not only possible, but very attainable, even w/ stock heads.
Are stroker kits worth it?
Yes, the kit is worth it. But you need to remember, pistons and rods and displacement are only part of the equasion to getting 500hp. You need to worry about getting the right ammount of air and fuel into the combustion chamber as well. A good set of heads, and the right cam make all the difference in the world.
How long will a 347 stroker last?
Seriously, I keep reading the 347 stroker is unreliable by design and to expect a long life from one, in a primarily street application, be it mustang or truck is not realistic. I think the general consensus is, you can expect it to live to 40-60,000 miles but by then it would be worn out.
Are stroker kits bad?
Yeah, strokers can hurt N/A power if not built right, because it lowers the rod/stroke ratio. If you build the motor with one, you can’t rev it as high because of the extra stresses put on the components.
Why do stroker motors make more power?
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.
What does Stroker mean in engines?
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 it bad to run engine at high RPM?
Excessive High RPM
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
Why do naturally aspirated engines rev higher?
NA engines must rev higher to produce a similar power output as a turbo engine does at lower revs. High RPM is not something that is good for an engine in terms of wear, or fuel economy. And the stresses on the engine parts are greater with high RPM than with increased manifold pressure.
How do you tell if a 350 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.
