STROKER KITS STROKER KIT

Why should I install a stroker kit in my engine?
When engines were designed at the factory the combinations that they came up with were designed to meet federal regulations while at the same time giving ample power to operate the automobile that they were being installed in.
For instance if a truck was designed at rated at say 6500 gvwr then the engineers for that model would come up with a combination in the engine of total horse power, tourque and cubic inches needed to operate this vehichle.
Lets say we have a truck was set up by Chevrolet with a gear ratio and drive train that needs 200 horse power to reliably pull a load of 6500 lbs at 75 mph(75 being the current speed for most of the U.S.A) at an rpm of no more than 3500.
The factory is not concerned with how fast the truck gets to 75 mph or if it will make power or go faster than 75. They are concerned with getting to 75 with the best fuel mileage at the least cost to them possible.If they can build an engine that puts out 200 hp at 8.0 to 1 compression with a .390-.400 lift camshaft with 350 cubic inches that meets these demands then that is what is built.
The engine combination could have easily made 350 horse power with a couple of changes to the compression ratio or camshaft or bigger cubic inches. Compression raito and camsahft changes have there good points as well as bad while changing the cubic inches can provide more power while retaining the every day drivability of the vehichle.
If you move the compression ratio from 8.0 to 1 up to 9.0 to 1 or higher you just changed the octane rating of the fuel that this engine has to be operated with in order give reliable performance without a detonation problem. (more information on detonation and octane ratings here)
Changes to the camshaft profile greatly change the whole performance of the engine as well as impacting the fuel mileage. To keep this simple in order to open a valve farther you have to have a bigger cam lobe to do it. If you have a bigger cam lobe you are holding the valve open longer and this is what causes the rough or loppy idle that you hear in performance style engines.
The best and most reliable way to make more horsepower and tourque is by changing the cubic inches of the engine. We have said if for years and I will repeat it here there is no replacement for displacement. No matter what you are trying to do the bigger the engine the more power it can make. We can make 450 horse power out of a 350 cubic inch Chevrolet the same as we can make 450 horse power out of a 454 big block Chevrolet the only difference being that the 350 has to be turning 6500 plus rpms with 12 or so to 1 compression ration and it is not a streetable engine. The 454 on the other hand can make this power at 10.0 to 1 with some good aluminium heads and a nice hydraulic roller camshaft and can be driven on the street with high octane pump gas.
Changeing from one engine family to the other creates alot of problems in making everything fit as the none of the manifolds, brakcets, pulleys etc are the same.
A Stroker kit allows you to use the original engine block and heads while changing out the internal parts. A longer stroke cranshaft usually involves changing out the connecting rods as well in order to maintain the proper rod ratio in the engine. The pistons in the stroker kit are made specifically for the new stroke and rod.
We have many different combinations that have been put together in our stroker kit menus to serve your needs from the truck that needs more power and torque for pulling to the all out race engine that needs the absolute most cubic inches that can be gotten out of a certain engine family.
