    There's a great deal of interchangeability among Chevy engines, transmissions, and rearends. These trucks have cavernous engine compartments, so engine.

    RPM also rebuilds and sells factory replacement short-blocks and long-blocks and complete engines for both Chevy and Ford applications. Dave bored the block to 0. We used a new set of valves, which were the same size as factory, using Sealed Power 1. The most deluxe, high-performance examples tend to take off first.

    In the realm of modified V-8 engines, none are more popular than Chevy's small-block. The funny thing is that all of them will be built differently. There are probably more recipes on how to build a small-block Chevy than there are for an apple pie. But if you talk to truck owners who have built one themselves, they often tell you that their engines turned out to be too expensive and end up with either too much power that they really can't use or not enough bottom-end torque to get the truck moving.

    How do you build the right engine for a specific 'wheeler? The answer will depend on the components used and how well they match the needs of the application. For example, a small-block in a '72 Chevy pickup that makes hp and lb-ft of torque will be less usable off road than if it were equipped with the same size engine making hp and lb-ft of torque. How is this possible? It depends on where and when the power is made. Heavier vehicles, such as pickup trucks, need a very broad horsepower curve.

    This means that power needs to be made from idle to as far up the rpm range as possible. On a lightweight vehicle, we can build an engine that will sacrifice some of the bottom-end power and use it to gain added speed at higher rpm. Although all of the engine's components make a difference in producing horsepower, the camshaft, the cylinder heads, the intake, and the exhaust system are key factors in placing the power at a particular rpm level.

    This is where many enthusiasts make their mistakes. Novice engine builders will often purchase components that are not meant to work with each other or components that are intended for high-rpm racing use. The end result is an engine that doesn't match the application. This is also true with some crate engines, where peak horsepower ratings are often the only information that enthusiasts consider before making a purchase.

    Matching the correct cylinder head, camshaft, intake, and exhaust systems will ultimately optimize the flow of air and fuel into and out of the engine.

    The design, in combination, will make dramatic increases in horsepower and torque. For example, smaller cylinder port configurations mixed in with moderate lift camshafts and dual-plane intake manifolds will create torque. Larger ports in a cylinder head combined with a high-lift, long-duration camshaft will make more top-end horsepower. What will work best in your particular application will depend on what kind of vehicle you are building. If you are looking for something to pull a trailer, you will want a lot of bottom-end torque.

    If you are building a high-performance on- and off-road truck that may see some moderate-speed prerunner action, you might want an engine with more horsepower. This means having an engine that will produce good torque at low rpm, while being able to pull strong at higher rpm levels. A simple experiment will show how two combinations of components will dramatically alter the power curve of a Chevy small-block - with a low budget and using available parts combinations.

    The first stage of the test would be to perform a simple, low-budget rebuild, suitable for a mild-performance off-road truck. However, we wanted all of the machining done to the highest quality.

    This process involves squaring all of the block and head surfaces and using a dial indicator to check the results. Our rebuild also incorporated as many of the original parts as possible, which increased the torque potential of this engine on a minimal budget. This meant using the existing heads, connecting rods, and crankshaft. The rebuild kit also contains many upgraded components. This camshaft profile characteristically improves low-end torque while still providing increased horsepower.
