Dart Marine High Performance 540 Short Block Engine Assembly

So let's face it you have numerous options when it comes to building your next High Performance engine. You could choose your local machinist Billy Bob with his antiquated old machinery, But lets stop and think about this for a minute. Who knows more about building a large cubic inch Big Block engines than the folks that actually designed the engine block themselves? And lets go beyond that. Let's stop for a moment and realize they got this knowledge from over 40 years of professional racing experience building these engines and winning championships all the while transferring all of this knowledge into their products..

Now imagine you can have not only the people that designed and make the engine block, but now you can also have them assemble the heart and soul of your engines short block, I mean this is almost PRICELESS. That right the same team of guys that builds 2000 horsepower competition engines is the same team that's building the your high performance short blocks for you!!

That's right you don't have to wonder if your some guinea pig at some shop that you don't know who did their machine work or for that matter the assembly. You can now have the best from the best. Now you simply choose from a wide array of quality engine components from the best in the business such as Callies Compstar, US Crankshaft, Mahle, JE, SRP, Clevite, Hastings,Total Seal,. Your desired combination will then be internally balanced and assembled into a brand new precision machined Dart Big "M" cast iron engine block. So the choices are yours build for your budget or build for your dream by the best in the business.
