“The Wise Guy”

The “Wise Guy” Chevy 383 stroker is a 400 HP crate engine built for everyday street driving and cruising. It has a good sounding cam, but more than anything it’s a solid, practical, reliable daily driver style setup. It has a little more sound and “peppy-ness” than the California Cruiser.

*All Parts are subject to change due to availability.  Substituted parts are of equal quality and durability to maintain advertised performance* 

Due to COVID-19, part available is constantly changing. Build times are usually 60-90 days on average right now.

Shipping rates are from $125 to $500 nationwide!

Shipping rates are all inclusive! Which means we can ship it to a freight terminal for pick-up, business, your installer, or your house for the same price… AND we offer pallet jack and liftgate services that’s included in the price already!

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.

For optimum service and purchase accuracy all quotes and orders are completed by phone. You can reach by phone at 1-888-957-5454 or email at!

Can you ship to my house?

Absolutely! We can ship right to your doorstep. The delivery driver will lower the engine from the truck with a liftgate and put it right in your garage with a pallet jack.

Do you ship internationally?

We accept international sales but the shipping outside of the USA is handled by the customer.

Can I pick it up?

For insurance purposes these engines must be delivered to you. These are big 500 lbs engines and we want a professional freight company to handle it with care to protect your investment.

How do I order?

Call us at 1-888-957-5454. We are open 9-5pm PST.

Do I have to pay upfront?

We require 50% down to get an order started and collect the remaining balance when the engine is complete and ready to ship.

“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!”
