We created this car engine cake for an 80th Birthday this weekend.  The cake replica of a Ford Model T Engine was sculpted in full size to match the original engine.  The best part of the story: the customers brought the 
actual engine to the bakery rather than supplying us with photos.  It was such fun perfecting the lettering, cylinders, and other engine parts.  

A fan was sculpted from sugarpaste, and then sugar bolts & screws were added - just like the real thing.  
The spark plugs to the engine were sculpted out of gumpaste with a flame on top to represent candles.  
Our final product measured 20" long by 16" wide and 16" tall.
The car engine cake was delivered to a party in Acushnet, Massachusetts.
