There tends to be some truth in the phrase "no replacement for displacement" when it comes to small or big block chevy motors. Adding displacement is the easiest and most cost effective way to increase horsepower throughout the entire RPM band. But with today's technologies and the machining modifications that we utilize at Eddies we can get impressive horsepower with stump pulling torque utilizing an engine as small as a 350. Lets Eddies Get Started On Your New Or Rebuilt Chevy Performance Engine: Before we get started it is important for us to understand what you will be using this engine for. One of the most important factors in designing an engine is that we must emphasize power and torque within the RPM band where the engine will spend a majority of the time. So will this engine be for a weekend warrior, drag racer, circle track racer, chevy truck, or basic street performance as an everyday driver? All these factors matter along with budgetary parameters and your application may be somewhat complex. Of course we'll help you make the right decisions that will fit your budget, produce power and torque and benefit the most enjoyment with your new engine. That's what we are here for! Rebuilding an engine can be a very rewarding experience, working with us and designing the engine for your car. When you work with us you will become familiar with what your engine is. Remember that it's important not to "overbuild" and to save as much money as possible. A common fault of many other engine builders is their inability to analyze their customers needs. This produces an expensive engine with exotic parts that will never be needed for the application and in turn can disappoint the customer and create buyers remorse. But at Eddies our plan is to create an engine for you that produces the most power for your application, but with cost in mind. Eddies will help you plan your engine for exactly the driving you intend to do. Our goal is to have a satisfied customer and this creates the word of mouth reputation that has made Eddies a top engine builder in the United States for over 35 years. Eddies Basic Chevy Performance Engine Rebuilding Information: It would probably take an entire website to get into detail the different small block and and big blocks that make each one special. But for basic purpose we'll concentrate mainly on the 350 small block V8. The most popular is the 350 with the 4.00 inch bore with 4 bolt main and this is the one we use mostly. Being in the engine building business for many years we have a nice collection of special blocks that we can use for your application and if we think you require a different type of block for speed/reliability, we'll find it. Once we get the block we thermally clean and steel-shot peen before checking it for cracks using magnaflux. The block is then bored with a Rottler Boring Bar and honed with a Sunnen CK10 hone. When all machining is finished, the block is pressure washed, then Clevite cam bearings and brass freeze plugs installed. This is our basic procedure on engine blocks.
Even with steel cranks there are more variations of material. Most small block chevy cranks are forged from 1053 steel, but the one we like to use that offer good reliability is the 4340 steel cranks by Scat or Eagle. These cast steel crankshafts will be used as needed for maximum strength and reliability. Our modifications to these crankshafts depending on your application are spin balancing and weight modification before assembly. The Connecting Rods - Connecting rods may be one of the most obscure parts when we build your chevy engine. They won't be responsible for producing globs of power but they are important for engine reliability and prevention of a costly overhaul later on.
Another area important area is the connecting rod bolts. We use a high quality ARP bolt that can resist pressure of over 200,000 psi. Using this high quality connecting rod bolt setup on your engine helps us ensure against any rod/cap failures. When setting up your engine the rods are resized using Sunnen honing equipment. Finally the rods are balanced to within 0.05 grams.
At Eddies we use hypereutectic pistons, which are cast aluminum pistons with a high silicon content. These pistons can withstand the higher RPM and cylinder pressures of the engines we build. The high silicon content of these pistons form as a temperature barrier which in turn retains more heat in the chamber and results in less thermal expansion over conventional alloy and stock cast pistons. At Eddies we use hypereutectic Keith Black or Speed Pro 10:1 compression pistons. For the high power engines we produce, we use a hypereutectic piston that are skirt coated to reduce friction at the extreme high RPM's the bigger power engines put out.
Moly rings boast superior seating time which guarantees a quick break in for the customer. They also produce exceptional seating and can whether all effects of changes in the combustion chamber.
At Eddies we like the design and ranges used by Crane or Competition Cams. These specific cams are used for their power increase and drivability. As hydraulic camshafts, these are self-adjusting to eliminate valvetrain noise. We then install a Manley true roller timing set to ensure accuracy during engine operation.
Basically there are cast iron and cast aluminum heads. Both have their advantages and disadvantages. We use performance cylinder heads with 2.02/1.60 stainless valves, bronze guides, multi-angle valve job, new valve springs, retainers, locks & seals, screw in studs and guide plates, are all used for maximum horsepower. Eddies utilizes port matching for optimized flow through the intake, as well as CC'ing intake volume, decking and truing. Remember this is the design of our low cost performance engines. When you get into racing applications this design all changes...dramatically! The Oiling System - As you may know there is much more to your engines oiling system than just the pan, pump and filter. Bearing clearances, oil galleys, windage trays restrictors and breathers all play an important part in a well designed oil system. Controlling the oil and getting it to where it needs to go and back again is an important part of your performance engine. While the stock oiling system works well with stock volume and stock pressure, your modified engine will require a different pump. While more pressure tends to help the lubrication of your engine it is important to point out that too much pressure requires more engine power to create. At Eddies we found through all our years of building engines that the Melling high volume oil pump, pickup, and drive rod setup work best to ensure proper lubrication to engine. The Rocker Arms - Depending upon your application we use performance long slot rockers arms in our basic engine packages. With our more advanced engine setups we use the roller rocker to further decrease valve friction. Quality Control With Your Engine Is Our #1 PriorityAt Eddies Performance quality control is an important factor in our customer experience. Careful measures in checking and double checking clearances is our precedence in producing a fast, reliable engine that will bear our responsibility.

The Engine Block - When it comes to building an engine you always start with the main foundation - the block. While it may appear that all small block or big block chevy engines use a few different blocks that generalization couldn't be further than the truth. There are over a dozen production based bore/stroke and main bearing diameter small block chevy cylinder blocks and well over 25 big block configurations we use. These all have different characteristics that are considered when designing your engine.
The Crankshaft - Getting into a more complex area of engine design we move to crankshafts. The good news is that most crankshafts are more than adequate for high performance street use. While we use cast steel crankshafts for most of our engines we also utilize the more exotic metal cranks.
If we are using stock rods or ones existing in your engine then magnafluxing is important. This process is used to find any surface cracks or fractures in the rod. If the rods pass the test, then shot peening is usually suggested. This surface procedure usually costs less than $50, but it reduces the chance of stress risers forming on the surface of the rod and could save you thousands of dollars later.
The Pistons - Tuning the induction, exhaust and cam timing is an all out effort to maximize turning the air/fuel mixture into heat and power. Pistons are what make all this happen and as with everything else in our engines and there are plenty to choose from. All the factors taking into piston consideration are the bore/stroke/compression ratio and ring combinations that are for your specific application.
The Rings - While all rings may look the same there are many different materials used in the industry. The poor cast stock rings are not to be used in any application and is susceptible to failure under detonation. While ductile or nodular iron is a better choice we still recommend and use the molybdenum rings.
The Camshaft - Since cylinder heads are the most important part of the engine, then we would have to say that the camshaft is a close second. The camshaft is basically the brain of the engine because it controls the air/fuel ratio by opening and closing the valves. There are so many variables when choosing a camshaft that is perfect for your needs and a novice or inexperienced person could get lost at all the choices out there. Thankfully enough you will have our experience to lean on when we design your engine.
The Cylinder Heads - There is no single component on your engine that is more important than your cylinder heads. While it's important that other parts play a major role in producing power the heads are key. We feel so strongly about cylinder heads that we spend hours upon hours modifying them to our specs in our machining facility. Because there are so many cylinder heads out there it would be tough to cover all the work we do on them.
