Choosing to purchase crate engine as an alternative to rebuilding an existing motor can be very smart. The cost associated with rebuilding a motor and heads cost a small fortune. Machine work is over a hundred dollars per hour. The machine work needed to complete a complete motor rebuild will cost in the neighborhood of four hundred dollars. You will need to have the heads ground and shaved, also valves will need to be lapped and seated along with valve guide reaming or replacement.

With the cost of small block rebuild kits becoming very expensive and combining the cost of the machinist work needed to perform a full rebuild the project is sometimes just not cost effective. The only time really that the approach of choosing a rebuild is cost effective is if the automobile is a collector’s item or rarity. Collectors’ items often have numbered engine parts that affect their value substantially if replaced with Crate Engines.
