Chevy 350 Crate Engine


Our “Hum Baby” Chevy 350 crate engine is our best-selling street-friendly engine for daily driving due to it’s dependability and price point.  It was nicknamed the “Hum Baby” from a TV star hot rod mechanic who said it was the smoothest running rebuilt Chevy 350 crate engine he’d ever installed.  He said, “This thing just hums! You should call it the ‘Hum Baby'”… and so we did!


It has an RV roller cam with a little bit of a lopey sound. It has plenty of vacuum and works with power brakes, A/C, and power steering.

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.

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.

I’m not on the West Coast, can I still buy from you?

OF COURSE!  65% of our business is done outside of California.  We can ship our engines direct to your door or to your mechanic in all 49 states.

How long does it take to receive my engine?

To build the engine it takes 2-4 weeks.  When the engine is complete we will call you to make sure that you’re available to receive delivery and to confirm all shipping information.  Once it ships, it takes 2-10 business days!

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.

Do I still get the 5 year warranty if I install it myself?

Absolutely!  After you complete your installation, have a professional mechanic assist you with your warranty paperwork, double-check all your work and sign it off.  It’s always good to protect your investment!

Do I receive any instructions with my engine?

Yes!  We have an engine break-in guide that will go over subjects such as oil filter recommendations, oil recommendations, where the timing needs to be set at, and other important information to help you with installation and maintenance.

“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

“Starting researching new motors. Went through all the big guys. Discovered Brady at West Coast Engines… was a little hesitant at first but he proved himself to be a righteous business man. Provided everything he said and service was amazing. Everything came on time. Easy to put in, friend and I did it, backed it up with a 700R4… this Chevy 350 crate engine is amazing, no issues, very smooth, I’m happy, and everyone I know is amazed with it even my mechanic buddies!” Daryll Goodman
