If you're a hard-core Chevrolet small-block engine guy, the good news about all the attention the LS engines are getting is there's never been a better time to build a budget Gen I small-block. That even applies to the nearly extinct small block.

Vigorously hoarded at one time, a few have appeared at the swap meet, and we even saw one at the junkyard not long ago. This prompted us to consider the ultimate budget tire-smoker when we received a scum-encrusted small block from Hot Rod's David Freiburger.

He swore it was good but abandoned it when he realized its value was declining faster than President Obama's approval rating. Other than the fact that it was a standard-bore block with stock parts, there was little to value in this casting.

In fact, our theory is he found the small block at the bottom of a deserted mine shaft under feet of boric-acid-laced water, explaining why our block looked hideous even after a hot tank dunk. The Chevrolet gods demanded an exorcism, but we ignored 'em. Even after an abbreviated sance in which the ghost of Zora Arkus-Duntov threatened to cancel our lifetime membership in the Bow Tie cult, we pressed on. Those were valid warning signs. We decided to build a motor in a way that all good car crafters would understand-by hacking the budget with a blunt instrument.

Sure, we took a risk by not boring the block and adding new pistons. The old pistons were in decent shape even after we beat them out of the block with a hammer! We even chose to ignore the serious rust pitting in the cylinder walls.

We were not deterred. We should have been, though, because the mechanical gods got the last laugh. Our power plan was as simple as it was cheap. We liked the idea of enhancing the 's strength of torque with a pair of Vortec iron heads and a budget flat-tappet cam to see how much grunt we could make.

Then we'd pump the power with a set of large-port Vortec Bow Tie heads. So now that you know the backstory, we'll fast-forward to the assembly effort, dyno testing, and subsequent bloodletting.

How to Identify a Chevy 400 Small Block

Assembling the Small Block The smart move would have been to bore and torque-plate-hone the block. But since the push was to hit this short-block cheaply, we decided to stick with the game plan despite evidence of neglect. So this is our worst-case scenario. As you can see from the honing photo, there is power to be gained from doing the correct machine work by boring the block to eliminate the bore wear.

We also kept to the bargain-basement plan with Summit's own cast-iron rings and basic bearings. We did have to grind the crank 0. Frankly, there's no way to really do this inexpensively.

Cam Specs The cam we chose was the least expensive hydraulic flat-tappet cam and lifter set from Summit that also included a dual pattern to better support the Vortec's well-documented weak exhaust-port flow. Vortec Heads The pivotal reason for resurrecting this was to create a budget short-block that could really enhance the 's inherent torque capacity.

Most everyone knows how good a bone-stock iron Vortec head flows. Did you know it's better than the old factory GM Bow Tie iron head? But there are some shortcomings as well. The stock Vortec head uses a very large-diameter valvespring guide that is also very tall, leaving barely enough room for 0.

Anything more crushes the retainer into the valveguide seal. Barrington machined our guides for 0. Unfortunately, this meant we had to purchase different valveguide seals because the Summit supplied seals are intended for 0.

All this extra machine work can be avoided by merely ordering a set of modified Vortec heads from Scoggin-Dickey that will come with better springs and the machine work necessary to clear most street cams. These are cc-intake-port heads the standard Vortecs are closer toand the small Bow Tie Vortec is ccand we've seen flow numbers upwards of to cfm at 0.The CID Chevy small block engine was produced from until and was the largest displacement engine made in that platform.

It was intended as a low performance, high-torque engine primarily used in Chevy's heavier passenger cars and light-duty trucks.

The general design was the same as earlier small block Chevrolet engines and incorporated many similar external features and dimensions while being internally different. The has gained notoriety — with modifications — as a powerful performance engine.

The CID small block engine kept the same external dimensions as the other small block engines, but increased its displacement through internal modifications. The engine shares the same length, width and height as other SBCs at approximately 28 by 26 by 27 inches respectively. Engine weight was also similar at about pounds. This engine shared the same ignition system — distributor, accessories and intake and exhaust systems as the smaller engines.

General Motors achieved the SBC engine's displacement by increasing the bore to 4. In contrast, the Chevy CID engine uses a bore of 4. GM had to cast the block for the CID engine differently to gain the extra displacement. Additionally, GM designed the crankshaft with larger main journals than the — 2. The connecting rods were also shorter than the others were — 5. It was available with both a two-barrel and four-barrel carburetor. While power output measurements changed in the early s from gross engine power to "net" ratings —at the rear wheels, output remained relatively comparable.

Gross horsepower ratings were at as much as horsepower while net ratings were little as This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information.

InChevrolet introduced the cubic-inch small-block engine into this environment, offering it for truck and large passenger car use. Although there were no high-performance editions of theit is currently popular to rebuild and customize the for high-performance applications, partially due to its availability and price.

The Chevrolet was produced from toand identifying it is a matter of locating and referencing the engine code suffix. Look for the engine code. According to the Chevy-Camaro website, the code is located on a machined pad directly forward of the passenger-side cylinder head, on the front of the engine block. A sample code reads "FCSB," with the first position designating the assembly plant, the second indicating the month, and the third marking the day of the month.

The following letters -- CSB -- are the suffix that will identify the engine when referenced to a Chevrolet suffix listing. Reference the engine code to a Chevrolet listing, similar to the one found on the When matched to this listing, the suffix code "CSB" is identified as a cubic-inch engine with horsepower, originally installed in a Chevy Caprice.

The Gen 1 Small Block Chev gradually grew to cid. To achieve this massive volume the bores were siamesed and the conrods were shortened.

The engine when produced in passenger car form had the same HP rating as the popular but it made more torque making it better for the heavy cars it was used in. I would like answers to clarify or dispell all the rumours. The general thought with the ci SBC is, when they are overbored by more than. This is not true. The overheating issue usually lies in the coolant passages sometimes considered steam holes which allow flow from the block to the head. These are very small holes which tend to get plugged up.

Cleaning these holes out usually helps with overall coolant flow and help prevents overheating issues. Another issue which may come into play with boring these blocks past.

Many of these blocks can accept an overbore of. There are reports of boring right through into water jackets with thin walls. A good wall thickness is said to be in the.

A third issue which needs to be addressed with these engines is to ensure they are honed with a torque plate installed and properly torqued with all fasteners. When this is done incorrectly or not done at all, these blocks are known to have oil control issues.

By placing the torque plates prior to honing after being bored overyou are ensuring the cylinders are completely round. This really applies to any block which you are having bored over. If a machine shop tells you not to worry about it or it doesn't really matter, take your business elsewhere, because this shop is lazy or doesn't know what they are talking about.The Chevrolet small-block engine is a series of V8 automobile engines used in normal production by the Chevrolet division of General Motors between andusing the same basic engine block.

Engineer Ed Cole is credited with leading the design for this engine. The Generation II engine is largely an improved version of the Generation I, having many interchangeable parts and dimensions. Later generation engines have only the rod bearings, transmission-to-block bolt pattern and bore spacing in common with the Generation I and II engines. Introduced as a performance engine inthe went on to be employed in both high- and low-output variants across the entire Chevrolet product line.

Over the years, every American General Motors division except Saturn and Geo used it and its descendants in their vehicles. Finally superseded by the Generation III LS in and discontinued inthe engine is still made by a GM subsidiary in Mexico as a crate engine for replacement and hot rodding purposes.

In all, oversmall-blocks have been built in carbureted and fuel injected forms since as of November 29, The small-block family line was honored as one of the 10 Best Engines of the 20th Century by automotive magazine Ward's AutoWorld. In February a Wisconsin businessman reported that his Chevrolet C pickup had logged over 1 million miles without any major repairs to its small block V8 engine.

Source: The Flint JournalFebruary 17, It quickly gained popularity among stock car racers, nicknamed the " Mighty Mouse ", for the then-popular cartoon character, later abbreviated to "Mouse". The was adopted by other Chevrolets, replacing the V8s. Installed in everything from station wagons to sports cars, in commercial vehicles, and even in boats and in highly modified form airplanes, it is the most widely used small-block of all time.

Though not offered in GM vehicles sincethe series is still in production at General Motors' Toluca, Mexicoplant under the company's " Mr. Goodwrench " brand, and is also manufactured as an industrial and marine engine by GM Powertrain under the " Vortec " name.

Of the three engines in this family, two of them, the and thehave gone down in automotive history. The first of this family was theintroduced in Cole's design borrowed the valve train design scheduled to be used at the time in the Pontiac V8. Internal GM rules at that time were that once an automotive division had introduced a technological innovation no other GM division could use it for a period of two years.
