Our “Hum Baby” Chevy 350 crate engine is a street-friendly 350 HP mild street performance engine.  We took the old generic 350 and fully upgraded it to last longer and have more performance than what GM and most other major manufactures in the industry offer.  We go that extra mile to ensure it’s nothing but the best parts, machining, blueprinting, and testing.

  • New Cast-Iron HD Vortec Heads
  • New Performance Roller Cam
  • New Hydraulic Lifters
  • New High-Performance Bearings
  • 1-Piece Rear Main Block
  • Name Brand Parts: Edelbrock, Holley, Fel-Pro, MSD
  • 5 Year/50,000 Mile Warranty

She 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!


Quality control – GM manufactures their engines out of Mexico and the quality control is inconsistent.  This is why you’ll see mixed reviews online.  It’s not that the actual build itself is more, they just setup their operation to be as cheap as possible.  Our facility is state-of-the-art with the best machinists in the area and the best equipment money can buy.  The same machining, parts, and build process that goes into our $12,000 engines is the same for this one.

Parts – Most of the biggest players in the industry are price-driven.  They get parts from overseas in large quantities to save money.  A West Coast Engines customer knows we are not the cheapest, but we are the best out there.  There’s no engine builder that does what we do: build high-end engines for your regular everyday “Joe” that wants a daily driver engine, customized, uses the quality brands we do, use the facilities we do, at the price we do, with a big 5 year warranty!  It’s hard to find a Chevy 350 engine out in the market with parts like Edelbrock, Holley, Fel-Pro, MSD, Weiand, KING, COMP Cams, and Melling.

Customization – Every engine is hand-built just for you.  You pick the paint color, valve covers, air cleaner, and other cosmetics.

Thoroughness – We have streamlined the purchase process to where you don’t need to know much about engines to do business with us because our sales staff is so highly trained that they can walk you through any technical process. Our team is always 3-steps-ahead when it comes to making sure you have the right parts that fit your vehicle.  It’s enticing to purchase an engine that’s sitting on the shelf at a retail store for $1,000 less but ask yourself: is it the right oil pan that fits?  The right flywheel?  Is there a flywheel?  Are there gaskets included and are they quality or will it leak?  Is it a flat tappet cam that will go bad in 15K miles or a roller?  There’s so much to know and so many ways to make a mistake if you don’t know engines.  Here we do it once and do it right so you never have to do it again!

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

“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!”
