What is the difference between a long block and short block engine?
They only differ in the components they carry. A short block package typically includes the engine block, crank and pistons. A long block engine has all the parts of the short block package. To the skeleton that is the short block, it adds a cylinder head, camshaft and valve-train.
Is a long block a big block?
A long block means a short block with the head(s) and push rods and lifters. A small block/big block designation is from GM engines. A small block was called a mouse motor and a big block was called a rat motor. The lines were blurred between a mouse motor and a rat motor.
What does long block replaced mean?
A long block is an engine sub-assembly that consists of the assembled short block, crankshaft, cylinder head, camshaft (usually), and valve train. A long block engine replacement typically requires swapping out parts from the original engine to the long block.
What is a long bare engine?
A Long Bare Engine is an assembled Engine Block with Cylinder heads without any front end accessories such as Camshaft gears, Timing Covers etc.
Is there money in rebuilding engines?
“While that can vary depending upon the shop’s particular situation,” Pfau responded, “the installation of a remanufactured engine provides an excellent opportunity for profit. In addition to the profit margin on the engine, the shop will make a profit on labor and accessory parts for the engine.
What is Big Block vs small block?
Though big–block engines are significantly larger than their small–block brethren, the true difference between these two is more about displacement, bore, and stroke than strictly size. Typically, big–block engines have displacements of greater than 400 cubic inches and small block engines have a smaller displacement.
Which is faster big block or small block?
Big block engines are larger in size and weigh more, but they produce more consistent power and torque to overcome the weight. Small block engines are smaller for better acceleration and handling, but more recently built models can be just as powerful as big block engines.
What is the best big block engine?

Are crate engines good?
Buyers of new crate engines experience far less problems than those who purchase remanufactured engines. Whether for stock or high-performance applications, new crate engines are more reliable and will give you the comfort in knowing that there are no used or refurbished parts in your engine.
Are used engines reliable?
Now, doesn’t that feel good? Replacement engines from quality engine sellers are either rebuilt or used, low mileage engines. This means that they will be reliable and ready to go for miles and miles. Don’t waste time and money on a new car when you love the one you have, just install a new engine!
What does a complete engine include?
A complete engine includes all of your hard internal parts as well as the fuel system, turbo, pumps, housings and oil pan. A complete engine can be bolted up and attached to the transmission rather quickly and requires no additional labor to work on the engine.
What is a bare engine block?
A bare block has none of the internals so it doesn’t have any pistons, rods, or a crankshaft in it. Next, we have the short block. Now this is a bare block, but it includes the connecting rods, the pistons, and a crankshaft.
What is align boring?
Line boring, which can also be called align boring, is a term used to describe an engine machining process. The task involved here is to create perfectly straight and aligned bores. These are used for the camshaft housing, which is also known as the saddles and tunnels, as well as the crankshaft.
What does bare engine mean?
An engine without fuel, oil, water, or any auxiliary devices such as vectored nozzles or APU (auxiliary power unit).
