what does it mean to stroke an engine? As in adding a stroker kit to an engine?

Answer 1

To stroke an engine means you are lengthening the "throw of the connecting rod". Say the piston's extent of travel up and down is 4" in a stock engine. If you change the rod so it is longer (or in some cases, use a crankshaft with a larger rod radius)and increase the piston's extent of travel to 4.5", you have stroked the engine. An engine with a longer stroke will produce more torque than a stock engine, but the big drawback is that stroking an engine usually requires a ton of machine work to verify the pistons and rods have adequate clearance from the block, camshaft, valves, etc. HTH!!

Answer 2

What are you trying to build into a stroker?? For the Chevy 350, its a 350 block, 400 rods, 400 crank, and 400 heads. That makes a true 383 stocker. But there are also the mouse motors, which are just backwards from the strokers.

Answer 3

Stroking an engine means making the piston go further by either putting in a crank with a longer stroke, or offset grinding the crank from that engine.

Changing the con rod won't stroke the engine, but you usually have to do that to get the piston to its optimum point at Top Dead Center, where it makes the most power..

Answer 4

It means to change the length of the piston arm to one slightly longer, to increase the compression ratio. Higher compression ratio creates more power. It also means you may have to switch to higher octane fuel, to prevent knocking. Because the piston moves closer to the head, you may have to switch to a more powerful spark plug with a shorter extention into the combustion chamber. You will likely create more pollutants.
With all the computer controls on today's cars, none of this may be possible. Change one thing in an engine, and it throws everything else off.
Old time street racers and hot rodders would bore and stroke engines to create more power or speed.

Answer 5

Thats impossible to know. Parts? I recommend that you buy a complete stroker kit instead of piece parting it. Power increase? What stroker crank are you buying? Crank forged or cast? Modified What is the final cubic inches? What pistons and compression ratio. What heads are you going to use? Are they going to be aluminum or cast iron How much money are you going to put into modifying the heads? What are the statistics on the cam shaft? Are you going to use a hydralic or roller cam? Are you going to spend the money for balancing and blueprinting? What intake are you going to use? What headers? Shorties = less hp

Answer 6

Increasing the engine displacement without boring it larger.

Changing the connecting rods to a longer length.
Probably using shorter pistons.
Changing the cranshaft to one that has longer 'throws'.
Probably changing the valve train and camshaft to increase the valve lift, duration and overlap timing.

Answer 7

that is when you take a chevy 350 and put a chevy 400 crank in it, then it becomes a chevy 383 stroker motor.

Answer 8

You are adding a kit that produces massive horsepower.
It is usually pistons rods heads and cam work.

Answer 9

Stroke is defined as the distance the piston moves from TDC (top dead Center) to BDC (bottom dead Center) up and down...

This distance to the stroke, is called "stroking"..

Answer 10

lenghten the connecting rods to the pistons.
