NASCAR Racing: Nascar engines, chevy ford, team toyota

Question
Harrison,
What can you tell me about Nascar engines? Are they custom built? Are they really Ford,dodge or chevys? Are they all the same size?

Answer
Well all of the Chevy, Ford, and Dodge teams build their engines at their shop or they buy hem from another team. Toyota builds all of their engines at TRD and gives them to the teams in the truck series.

All engines are the same size. There all the same except for certain parts on the engine that distinguish them from each other. The manufacturer supplies those parts to the teams and they assemble the engines.
