GM Crate Engine Buyer’s Guide for Hot Rods & Street Rods

PACE_edited-1 [1]

These days there are a number of crate engines that can provide you with a dependable driver. Aftermarket companies are producing a multitude of parts, various components and even full-on race engines in crate form. If you’re looking to go fast, have a shiny engine for your show car or just a dependable mill for your daily driver, and do it on a ramen budget, a crate engine may be exactly what you are after.

Pace Performance is a complete one-stop-shop for everything Chevy. From pink engine dress-up kits to hardcore racing crate engines. [2]

Pace Performance is a complete one-stop-shop for everything Chevy. From pink engine dress-up kits to hardcore racing crate engines.

Why Buy a Crate Engine?

Generally speaking, defining a crate engine is simple and for our purposes, “crate engine” refers to an engine that’s shipped complete, at least up to the cylinder heads. There’s really no drawbacks to a crate engine. Largely they are very affordable, built by engine builders that know what they are doing, have a warranty that backs the quality of the product, and all you have to do is drop the engine in and go.

Building your own engine may inflate your value of self-importance, but there’s really no beating a combination that has already been developed and tested like a turn-key crate engine.

Crate engines are not a new idea. For years GM Performance, now Chevrolet Performance [3], have been producing affordable crate engines for cheeseburger budgets. More recently, Pace Performance [4] has gotten into the game of supplying the aftermarket with fully assembled crate engines to fit into any budget. This buyer’s guide will deal strictly with crate engines designed specifically for the Hot Rod, Street Rod or mild Street/Strip Rod.

Crate engines from Pace Performance are built by professional engine builders with aftermarket parts from companies that are known for quality and consistency. Most of Pace’s crate motors come with a great warranty to back up your purchase, which adds an extra level of comfort in the purchase.

How to Select a Crate Engine?

“The first consideration when selecting a crate engine has to be the application,” says Chuck Fitch. “If you have a daily driver, you probably are looking for a crate with EFI for fuel economy, power and superb dependability.” Companies like Holley [5] and MSD [6] are making quality EFI systems that are easily added to the Intake system of a SBC or LS engine.

pacelogo [7]Price is always a consideration for buying an engine or having one built. Crate engines gained popularity by providing decent power at a budget price point and this has continued to be the norm. If you want a base small-block Chevy, a crate engine will cost you less than building the engine yourself with the same caliber components, and don’t forget, the crate engine will be backed by a warranty. Fitch told us, “Before a customer spends his hard earned money on a crate engine, we want it to be the right one for his ride.”

Durability is an important factor for most crate engine buyers. “Unless they are people that like to work on engines, a customer is going to want an engine that is going to live for a long time,” says Fitch. “Many crate engine customers want an engine that runs reliably on pump gasoline. Our 10:1 and lower compression engines will keep the fuel cost down because you don’t have to buy expensive racing gas.”

There are a lot of specs and stats that get published on every engine built. Most consumers are looking at the peak horsepower number but not the torque number. Many of the crate engines have a similar horsepower range but some of them have substantially more torque. At the low end, Torque is what gets the vehicle moving. If you want the car to move faster at lower rpm, shop for an engine that has a higher peak torque in the lower rpms. 

How Does Pace Performance Build Their Crate Engines?

Pace Performance also has the tech department to help you get the exact part you need. From measuring an LS engine crank pulley to finding the right crate engine for your application. [8]

Pace Performance also has the tech department to help you get the exact part you need. From measuring an LS engine crank pulley to finding the right crate engine for your application.

“We start with a great base to work with, primarily with a Chevrolet Performance crate engine,” explains Fitch. Using the Chevrolet crate engine as a base makes a lot of sense. As Fitch explained to us, “The factory built crate engines go through durability testing on the parts and assembly. Most aftermarket companies are not subject to this same level of scrutiny. We can take this dependable foundation and build upon it,” he said. “We can tailor the crate engine even further by using quality parts from Holley, MSD, PROFORM, Edelbrock, FAST and a few others. This helps us offer a custom engine right off-the-shelf.”

Buyer’s Guide

The crate engines that you will see here include small-bock Chevy engines and LS engines which come complete from carburetor or EFI to the oil pan. Categorizing crate engines is a difficult chore because one engine may cross categories and be applicable in different applications. We’ve broken it down to four basic categories: Gen I SBC Carbureted, Gen I SBC EFI, LS with Carburetor and LS with EFI. With some guidance, we put these crate engines in the category that fit them best, with a budget, midrange, and king-of-the-road models. For fun, we have also picked a couple of unique and special crate engines from pace that caught our eye.
