    Overall Assessment

    Customers appreciate the mock engine block for its practicality in custom chassis builds, noting its usability, quality, and safety attributes. The product's lightweight design enables easier management, reducing physical strain compared to a real 600 lbs engine. It saves time, negating the need for a hoist and simplifying verification of space limitations and design concepts. The mock block minimizes fabrication errors due to guesswork, proving indispensable in engine/trans setups. Users express satisfaction and affirm they should have invested in it sooner.

    Finally broke down and bought my first mock engine block. Makes everything so much easier when building a custom chassis/ride. The time saved not using a real heavy block and hoist is only the surface benefit. Having the ability to quickly verify space limitations, design concepts etc. led me to using it far more than expected. It also cuts down on fabrication time with "hit or miss" trialing by trying to guess fitments.

    Would Recommend

    Great for engine/trans set up.

    Much easier to manage engine/trans set up rather than 600 lbs. of the real thing!
