Frequently Asked Questions on our Stroker V8 Engines
What is a Stroker Engine.
Stroking an engine is basically increasing the engine’s stroke length by converting over to a longer stroke crank. Take for instance the 302 Ford. A very popular conversion is to go to a 347. The factory stroke of the crankshaft is 3.0 inches to make it become a 347 the stroke is extended to 3.40 inches in length. You need to utilize a different length connecting rod also. Engine Factory can supply you a stroker with proper machining , balancing and notching of the block to make it trouble free. The nice thing about this set-up is that all the modifications are done internally so your mounting patterns and accessories will all be identical .
Why are these engines more expensive than your other motors?
Typically these run about $1,000 more than the non-stroked engines. When you have an increase in Horsepower and torque it's critical that the internals are up to handling it. So we use forged pistons, Steel or cast steel cranks, Steel Beam Conneting Rods. This of course adds to the price tag. These engines can be used more for Street/Strip applications and can withstand some more wear n tear being that the internal parts are stronger.
What difference will I feel in real world driving from a stroker to a non-stroker engine?
Whenever an engine is given more leverage and cubic inches it is going to deliver more torque which is exactly what every street performing vehicle needs. This will give you the grunt seat of the pants, plant you in your seat feeling without going to a larger sized engine. Piston velocity in a stroker engine is greatly increased, resulting in a intake charge which continues even past the point of Bottom Dead Center. This equates to more cylinder filling which then creates more Horsepower. A gain of 75lbs. more torque over a "non-stroker" engine is often the case.
Do some Stroker engines use more oil than conventional engines?
On the technical end of things, There is a misconception that if the Piston Pin protrudes into the oil rail area that the motor will suck down oil. This is a completely wrong assumption when using quality pistons. Oil will just drain back into the oil supply. Most every top Piston Manufacturer designs their stroker pistons this way. The SRP Power Forged pistons that we supply the most are designed to be more rigid, Run tighter clearances and oil control is excellent with the correct Rings used.
