Smart consumers buy 383 stroker crate engines at West Coast Engines because they offer more value for their money. We put more research & development into our engines, offer bigger warranties, better quality parts, and aim to deliver complete engines dyno tested and ready for an easy installation.

No racing engines here! We build reliable street-friendly engines for your everyday Joe who wants to take his or her hot rod for a cruise on the weekends and have some fun


Starting on the top-end we use aluminum that has 205cc runners/64cc chambers. The lopey sounding Trick-Flow camshaft incorporates a hydraulic roller (part number 31403001). Elgin Industries supplies our self-adjusting steel roller rockers with ARP studs and a COMP Cams valve train.

The bottom-end has a Scat 9000 steel crankshaft rated up to 500 HP, GM forged rods, ARP rod bolts, and Keith Black pistons with Hastings rings.

On top of the engine is a Performer RPM Edelbrock intake with a 770 Street Avenger Holley carburetor. Get your fuel injection upgrade with a Holley Sniper EFI system! MSD Street-Fire HEI Distributor, MSD wires and BOSCH spark plugs completes the upgrade.

Every engine is machined, balanced, and blueprinted at our factory to ensure it meets our highest standards. With a Turnkey or Drop-it-in-and-Go package, we hot run and dyno your engine for up to 1 hour with all your equipment installed. This break-in procedure ensures all your new parts are working up to standard with no leaks or defects.

Aluminum heads are more durable and lighter than generic cast iron heads (also known as ‘steel’ heads). Aluminum heads last longer because it’s a

more durable material made with the latest technology in precision machining and cast molding. This allows the engine to run cooler and ensures tougher heads that produce more power!

When purchasing an engine online or even in the retail world, it comes as-is with no options. It will be painted black with one style of oil pan, no flywheel, no gaskets, generic intake manifold, generic carburetor, and a warranty that has so much fine print it’s essentially not a warranty whatsoever.

Here at West Coast Engines your engine is fully customized and built-to-order in just a few weeks.  This allows us to accommodate the right oil pan, flywheel, engine color, intake manifold, smog equipment, or anything else that may be important to you! We can also customize the packages if you already have a carburetor or an ignition system and simply deduct it from your order. That way when the engine arrives it’s a QUALITY product that LOOKS, SOUNDS, and PERFORMS the way you want it, making every dollar spent worth the investment.

“This engine has so much more performance and fuel economy it’s unbelieable. They were extremely helpful and the engine builder was so knowledgable. Was a great experience and I would do it 100x over! I was referred to West Coast Engines by a mechanic buddy of mine that has been in car racing for 30 years. He’s been doing business with Brady for hot rod engines for years. Anyone that’s interested in performance engines that are street friendly and run on regular gas this is your place.”

Gerald Frazier

“I bought my stage 5 engine from West Coast Engines and I could not be happier with my decision. It is the perfect setup for my 56 Chevy truck. After weeks of research and several conversations with Brady, I determined that he was the most informed and knowledgeable person that I spoke to in my search for the right powertrain for my truck. I recommend anyone who is building a car or truck that wants the peace of mind that goes with having a full warranty on a bad ass engine, to call the guys at West Coast Engines you will not be disappointed!”
