Just based on the name, many believe the big block engine is better, but size isn&rsquo;t the only thing that matters when it comes to engines. In fact, you&rsquo;d be surprised by just how much power a small block engine is actually packing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Small Block Engine?<\/h2>\n\n\n\n<p>As its name suggests, a small block engine is a block engine with small bores, strokes, ports, and valves. It weighs a lot less than a big block engine, but it can generate up to 5800 <a href=\"https:\/\/www.carparts.com\/blog\/what-does-car-rpm-stand-for\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"revolutions per minute (RPM)\">revolutions per minute (RPM)<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">History of Small Block Engines<\/h2>\n\n\n\n<p>The first small block engines to hit the market were the <a href=\"https:\/\/www.carparts.com\/chevrolet\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Chevrolet\">Chevrolet<\/a> Series D V8 engines. Produced from 1917 to 1919, they unfortunately had a short lifespan, but they encouraged other companies to produce their own version of the Chevy small block.<\/p>\n\n\n\n<p>Soon enough, <a href=\"https:\/\/www.carparts.com\/ford\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Ford\">Ford<\/a> released the powerful Flathead V8, which quickly became popular among mechanics and car enthusiasts alike. By 1955, Chevrolet debuted their new and improved small block engine called the &ldquo;Turbo-Fire&rdquo;, which was two times more powerful than the other small blocks on the market. People started calling it the &ldquo;Mighty Mouse&rdquo;.<\/p>\n\n\n\n<p>It didn&rsquo;t take long for General Motors (GM) to develop other versions of the small block engine, but the last of the original small blocks were discontinued in 2003.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/09\/chevy-d-v8-engine-1024x680.jpg\" alt=\"chevy series d v8 engine image\" class=\"wp-image-91136\" width=\"1024\" height=\"680\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/09\/chevy-d-v8-engine-1024x680.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/09\/chevy-d-v8-engine-300x199.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/09\/chevy-d-v8-engine-768x510.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/09\/chevy-d-v8-engine-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/09\/chevy-d-v8-engine.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>A small block engine is a block engine with small bores, strokes, ports, and valves that weighs a lot less than a big block engine but can generate up to 5800 RPM.

Here are some examples of their other differences:<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Displacement<\/h3>\n\n\n\n<p>Back then, a small block engine typically had a displacement of less than 400 cubic inches, while a big block engine could measure over 400 cubic inches. While this doesn&rsquo;t necessarily mean a small block engine was less powerful, it did mean it had less air and fuel intake than an average big block.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bore and Stroke<\/h3>\n\n\n\n<p>Unlike big block engines, small block engines have larger bores and smaller strokes. This means they typically have less displacement, but they can rev faster than big blocks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Size and Shape<\/h3>\n\n\n\n<p>With just one look, you can probably tell a small block engine from a big block engine. A small block engine is physically smaller than a big block, and it also has a distinct V shape.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pros of Small Block Engines<\/h2>\n\n\n\n<p>Don&rsquo;t underestimate small block engines just because they&rsquo;re small. They actually come with a lot of advantages that make them a popular choice for many drivers. Here are some examples:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lighter<\/h3>\n\n\n\n<p>Small block engines are a lot lighter than big block engines, which means they can make a vehicle feel much lighter too. There&rsquo;s less pressure on the front axle, making vehicles with a small block engine easier to handle and faster than vehicles with a big block.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Consumes Less Fuel<\/h3>\n\n\n\n<p>Lighter vehicles are typically more fuel-efficient than bigger vehicles, and small block engines are no different. With smaller cylinders, small block engines use up less fuel than big block engines, which is not only better for the environment but also for your wallet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Less Expensive To Fix<\/h3>\n\n\n\n<p>Because they have fewer parts than big block engines, small block engines are also much cheaper to repair. You&rsquo;ll have fewer parts to maintain too, so you can expect to save on both time and money when it comes to these smaller engines.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cons of Small Block Engines<\/h2>\n\n\n\n<p>No engine is truly perfect, even if it&rsquo;s as compact and cost-efficient as a small block engine. Here are some of its disadvantages:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Less Torque<\/h3>\n\n\n\n<p>While small block engines are great for sports cars, they&rsquo;re a lot less practical for larger and heavier vehicles. Small block engines typically produce around 220 to 350 lbs-ft of torque, while big block engines can reach well over 500 lbs-ft of torque.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Less Horsepower<\/h3>\n\n\n\n<p>Small block engines aren&rsquo;t all that great at producing horsepower too. With smaller bores and shorter strokes, they offer less horsepower than big block engines. A small block Chevy can produce around 145 to 370 horsepower, which pales in comparison to the average 430 horsepower of a big block engine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Vehicles With Small Block Engines<\/h2>\n\n\n\n<p>As great as small block engines are, most of them have been overshadowed by powerful big block engines. However, this doesn&rsquo;t mean small block engines weren&rsquo;t popular in their own right. Here are some examples of popular vehicles with small block engines:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.carparts.com\/chevrolet\/corvette\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Chevrolet Corvette&nbsp;\">Chevrolet Corvette&nbsp;<\/a><\/li><li><a href=\"https:\/\/www.carparts.com\/dodge\/challenger\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Dodge Challenger\">Dodge Challenger<\/a> T\/A<\/li><li><a href=\"https:\/\/www.carparts.com\/ford\/mustang\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Ford Mustang\">Ford Mustang<\/a> K-Code<\/li><li>Shelby Cobra<\/li><li>Studebaker Avanti<\/li><\/ul>\n\n\n\n<p>Some of these vehicles have unfortunately been discontinued, but you can still find some of them being sold for thousands of dollars. However, there are some that have stood the test of time, such as the Chevrolet Corvette and its 350 small block engine, which are still being produced to this day.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Small Block vs. Big Block: Which Engine Is for You?<\/h2>\n\n\n\n<p>People often debate over which engine is better, but the truth is that it really depends on what you&rsquo;re looking for. Small block and big block engines both have their own pros and cons, so it all comes down to what you want from an engine.<\/p>\n\n\n\n<p>If you want more power at the cost of pricier repairs, then a big block engine might be for you. However, if you want better acceleration and handling, then a small block engine is the way to go.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 4<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>Car enthusiasts love to debate over what the better engine is: a small block or a big block engine.
