Engine Block Purchasing Tips

Cylinder Block Tips

When it comes to purchasing an engine block, there are some basics that you as the consumer need to know. In this section of our website we will do our best to prepare you to ask the right questions and how to spot a dud. Ultimately we want to save you money on your engine block purchase while also helping you to avoid the grief that comes along with making an misinformed decision.

First, you must consider where the engine block has been stored. It is not uncommon for bare blocks that have been sitting outside to simply rust into worthlessness. Even after a large overbore, cylinders may still have large pits making it difficult for rings to seal. Lifter bores may also contain pits. A little rust is one thing, since a bake and shot blast job can clean that up. But it is a different story if the block is so deteriorated that the machine work needed to correct it would be cost prohibitive.

Has the engine block you are about to purchase been machined? This is one area where many sellers respond by saying "I don't know." Be cautious of these situations. An engine block seller can easily obtain a pair of calipers and tell you whether or not the engine bore is standard, .030 over, or even .060 over. Especially engine blocks that came from a performance engine, you may also encounter deck heights that have been modified, align bores or hones which would require an undersize timing chain, and so on. Get the facts before you buy a used or remanufactured engine block. Of course if you are buying a new engine block, this is not as major of a concern.

If the engine block you are purchasing has been machined, ask if there is any return policy should the specifications be out of tolerance after an inspection by your machinist. There's is nothing worse then spending hundreds, or even thousands of dollars, on a remanufactured engine block only to learn you must bore and hone the cylinders or align hone the block.

As with any engine used or engine block you obtain, it is good practice to fully test the engine block before using it to power your next engine. Automotive machine shops can normally help you with this by providing sonic testing, magna flux services, and/or pressure testing. The cost of testing your purchased engine block for cracks and defects is minimal and can ultimately save you a lot of money.

Shipping costs for engine blocks can be expensive. Generally speaking anything over 150lbs must be shipped by a freight truck. Depending on the engine block you are purchasing, you may be able to have it delivered using standard ground services. But if you are purchasing a short or long block, expect a freight charge of $250 depending on where you live.

We hope these tips will help to make your engine block purchase easier and give you the confidence to negotiate the best price possible. No matter what, always do your best to make the sale contingent on inspection. Should and engine block you purchase have flaws, make sure the seller does have a return policy.
