Looking for an engine block online can help automotive enthusiasts quickly locate the block they are looking for. However, one must ask the needed questions prior to purchasing this often costly engine part.
There is no shortage of engine blocks being sold across the web. Some of these blocks may have defects or damage that makes them unusable, which is why it is so important to ask the correct questions before the purchase.
When purchasing a block online, it is extremely important to determine what size the cylinder bores are. For example, a .040" over-sized block may have no piston and ring purchase options available to an engine builder that would like a newly machined bore and hone on the cylinder bores. Another ideal question to ask is if there was any damage to the crankshaft, which could influence the align bore specifications on the engine block. Finally, the person interested in purchasing an engine block should determine if it has ever been stored in an environment where it may have froze. An block that has been frozen could result in the block being damaged by cracks. The condition of the engine block, and its present tolerances, directly decides how much machining will be required and if the block can even be machined at all.
There are quite a few blocks available for purchase in online auctions that have already been machined. Whether it’s a Ford engine block, or foreign made block, the shopper should determine the quality of the machine work that was performed on on the engine block. Most machine shops can hold close tolerances. However, there are many that can't. In fact, there are sellers which will simply hone a few extra thousands oversize to leave a visibly clean crosshatch in each cylinder bore.
The shipping expense for shipping a block can be costly. Many L4 engine blocks weigh over 90 pounds. The time in transit an engine block must travel between the buyer and seller also impacts the shipping cost. Engine block buyers should expect to spend a minimum of $80 for shipping and insurance. If possible, buyers should try to negotiate free or discounted transport with the seller.
Engine builders purchasing an engine block online should be fully prepared to degrease and thoroughly inspect the block. The inspection routine must include looking for cracks, in addition to determining the present size of each cylinder. If the buyer needs to take the engine block to their local machine shop for inspection, it is preferred over building an engine that is destined for failure.
