A superfan of Big Boy 4014 has submitted a motorized, 3,920-piece Big Boy 4014 LEGO kit to the company. If his idea gets 10,000 votes, it will be among designs advanced to LEGO’s review pool for potential production.

Big Boy fans have 500 days to support Dupon's project. 

With nearly 4,000 pieces involved, the model is also complex to put together, requiring 987 pages of instruction.
