I am wondering, since i am very fluent in the anatomy of lots of really old car engines, like old 1920's era Inline 4 and 6 F and L heads, the first ford L head v8's, i could even try modelling the parts for the very first cars, like T head engines, etc... i'm wondering, can you like, make the part in blender or google sketch up and import it into the game's editor and try to give it performance values, one part at a time?, thanks.
