Welcome to Promar Performance Engines!

By choosing Promar Performance Engines for your high performance engine/crate engine needs you are selecting the highest quality performance engine on the market. All of our quality work is done “In House” we do not rely on other’s to supply us with our short blocks or balanced rotating assemblies like so many “performance engine shops” do. We are not part of a large “assembly line” performance engine company where performance just gets lost in the shuffle. We are your full service Performance Engine Shop with our years of experience and quality backing us up.

Here at Promar Performance Engines we offer a full line of Performance Crate Engines and Custom Engines. Our High Performance Crate Engines are designed for increased horsepower and torque with a price that won’t empty your wallet. If you need more serious performance or are looking for something specific just give us a call or click on the link to the left to quote you a Custom Performance Engine.

When you look at our competitive prices keep in mind to look at the quality of components that go into every one of our Performance Engines / Crate Engines. The high quality components that we install are there to give you years of worry free reliable horsepower. We feel that there is no reason that you should have to settle for less than the best, which is why we build our Performance Engines the way we do.

We offer several levels of Performance Engines.

To see our more popular designs click the “crate engines” link on the left.

High Output Performance Engines: Moderate performance increase from OE. These are perfect for your daily driver or for a Performance Engine on a tight budget.

Stroker Engines: Increased cubic inch and performance without the cost of a racing engine. These are ideal for Street, Truck, Restoration, or Muscle car applications.

Street/Strip Stroker Engines: A stroker engine with forged internals for increased strength and durability. This is the perfect performance engine for customers that want the most on the street and at the track.

Racing Engines: These are for the racer that wants a big cubic inch, high compression, and forged internal performance engine with high horsepower and torque output.

Marine Performance Engines: Large cubic inch Marine Engines for more horsepower and lots of torque to get your boat up on plane faster.

We are experts in performance engine /classic engine restoration projects taking your “serial numbers matching” engines and restoring them back to original performance or increased performance levels.

Promar’s definition of terms.

High Performance Long Block Engine
This is the basis for all of Promar’s Performance crate engine packages. A long block includes a block, a rotating assembly, a pair of heads, and the valve train. If you already have the rest of the items to complete your installation this is the most economical choice. Just remember to clean all of your old parts thoroughly.

Crate Engines
Performance crate engines from Promar include a performance long block engine assembled with an oil pan, a harmonic balancer, a pair of valve covers, a timing cover, an intake manifold, and a flex plate. You would want to choose a crate engine if you are not sure what components work well together or if you don’t want the hassle of cleaning all of your old parts that may be warped or damaged. Our Crate Engines not only save you time, they look great too!! All of our crate engines can be customized to your specifications.

Turn Key Engines
Our Performance Crate engine with a turn key package includes everything in our crate engine packages plus: a carburetor, a distributor, a set of spark plugs, a set of plug wires, a water pump, and a fuel pump (if applicable). This performance engine is the way to go when you have a clean slate and want to start with all new parts.

Crate Engine Completer packages
Our Completer packages add the little extras that you want to finish your engine installation project. These include a PCV valve, Valve cover grommets, valve cover breather/s, PCV hose, fuel lines (from Fuel pump to carb), in line fuel filter, oil filter, and an Air cleaner. Most customers want to purchase these items themselves because everyone likes something different, but we offer this as an option.
Completer sets start at $99 and up (depending on application)

Crate Engine Aftermarket Accessory Kits
These Kits are the ultimate in finishing that High Performance Crate engine. Imagine dropping 600HP into your baby and expecting to run a factory v belt setup for your accessories. Aside from the fact that you will be spinning belts and throwing them off left and right they just look bad. We offer incredible looking serpentine belt kits for most make and models of performance crate engines. We carry Concept One and March Performance brands. Prices range from $899-$3999 depending on engine design, accessories and desired finish.
