Stroking a 350 could be putting a 305 head on it?
Stroking an engine means changing to a crankshaft with a longer stroke such as putting a crank from a 400 into a 350 block. Changing to a different head could change the compression ratio and the amount of flow through the intake and exhaust.
A good sentence for compression?
As a result of wear and tear there was no longer enough compression in the cylinder heads to keep the motor running.
What advantage of milling engine blocks?
A smooth, flat surface seals better, and the head gaskets last longer. Also, a smaller combustion chamber would increase the compression ratio.
Main advantages and disadvantages between compression ignition and spark ignition engines?
A spark ignition engine is a gasoline engine. A compression ignition is a diesel engine.basic difference between compression and spark ignition engine is ,compression ignition is a diesel engine. spark ignition is a gasoline engine.diesel engines compress the fuel to a point where the fuel explodes, thus giving ignitiongasoline does not compress to explosion, therefore it needs need a spark to ignite the fuelspark ign. is gasoline. comp. ign. is diesel.A compression ignition engine is typically a diesel. It compresses air so much that the heat from the compression is enough to cause the fuel to ignited once injected. A spark ignition engine is your average gasoline-burning car engine. It uses a spark plug to ignite the air/fuel mixture instead of relying on compretssion ignition.A compression ignition engine uses very high compression of the air to heat it self up and the fuel is injected into the cylinder which self ignites (a diesel engine is a compression ignition engine).A spark ignition engine uses a lower compression ratio and requires the use of a spark to ignite the fuel (a petrol engine is a spark ignition engine).Because the oils used for a diesel have a higher calorific value, they have a better fuel economy, They also do not need extra energy usage to keep the engine running, unlike the energy that is lost to power the spark plugs from the generator/alternator which is taken from the useful energy produced by the engine.
Why does a diesel engine develop more torque than a gasoline engine of equivalent displacement?
Diesel engine runs at a higher compression ratio than a gasoline engine. A typical diesel engine may also use a longer stroke and smaller bore than a gasoline engine. Diesel fuel has a higher energy density than gasoline.
What are the Reasons for stroking engines?
the main reason for stroking an engine is for what else, more power. when you install longer rods or a longer throw crank, you change the length of the "stroke", which pushes the piston closer to the head, resulting inhigher compression, and more power.
Is it ok to have compression shorts longer then shorts?
yes but it is not very fassionable.
Will a vortec engine install easily in a 1980 Chevy scottsdale?
You will need an after market Vortec Intake None FI 4BRL set up. The vortec engine has longer runners to increase air speed for the vorteciy action of the heads.
Why desiel engines will give more milage when compared to petrol enginess?
They are simply built much tougher. Diesel engine have a compression ratio that is much higher than any petrol engine. As such the internal parts must be built stronger to handle the higher compression. Also the diesel fuel itself provides some lubrication. These factors provide for a much longer life.
Which force squeezes Earth's crust to make the crust longer and thinner?
compression
Is tension boomilever stronger than compression boomilevers?
Yes. This is because the strength of wood when compressed, decreases per length unit the longer the piece of wood is. However, wood holds the same strength in tension no matter the length. In the compression boomilever, the compression chord is longer than in the tension boomilever.
What is the pushrod placement for a 1998 Pontiac grand prix 3.1 engine?
The exhaust pushrods are slightly longer than the intakes. To locate where to put the shorter intake pushrods look in the bores in the cylinder heads where the intake manifold lines up and you'll see the intake valve. Simply place all the short pushrods where you see the intake valves and you should be able to find where to install the rest.
