We named our 347 stroker “Balboa” after the famous Balboa Peninsula and Balboa Island in Newport Beach, California. A historical landmark where you’ll often find classic cars and it feels like your back in the 50’s with the local small antique shops, ice cream parlors, and beach cruisers.

This 347 stroker is for cruising the streets and long distance driving. It’s plenty of torque and power for some fun but not overkill.


  1. Every engine is custom hand-made and we offer custom valve covers, paint jobs, fuel injection options and more so we can help you build your dream engine that fits within your budget and lifestyle!
  2. We use only the best name brand parts that are reliable and long lasting. Names such as Scat, COMP Cams, Holley, Edelbrock, Trick-Flow, AFR, ARP, Fel-Pro, and more. No cheap parts here!!!
  3. Big 5 year/50,000 mile warranties that include parts and labor, covered world-wide, and covers self-installs.
  4. Wide range of packages from a long block to a complete turnkey engine that’s drop-in-ready to install in a matter of a couple hours that’s already dyno tested and tuned for you with AC, powersteering, starter, and more!


Let’s start with the power, it’s right in that sweet-spot all the Mustang owners are looking for: 440 horsepower and 440 torque!  She’s built to be a street-friendly everyday driver (not racing) and runs on 91 premium gas.  It’s a direct replacement for any 289 or 302 Ford engine using the same mounts and no fabrication or conversion kits whatsoever making it an easy installation into your Ford Mustang, Ford Falcon, or classic Ford truck.

No cheap stuff!! We do nothing but the best: Scat, COMP Cams, Holley, Edelbrock, ARP, Fel-Pro, and more.  Fully CNC machined, balanced, and blueprinted engines.  To top it off, this engine is backed with a 5 year/50,000 mile nationwide warranty! Consumers shop at West Coast Engines because we go the extra mile, they are guaranteed to get it right the first time. Ask ANYONE who’s done business with us and they’ll tell you the same.

You’ll also notice we have custom paint colors, fuel injection options, air conditioning options, and more.



Any classic Ford trucks and cars from the 1930’s to the 1970’s! This is for the old-school carbureted engines, not 1990’s and newer. Great fit for Mustangs, falcon, and trucks,
