So, besides the Engine stuff, Are there any other general differences in the 300 and 400? I know the 400 has a V8 but other then the subtle sizes in engine, are the bodies pretty much the same? 400 comes with a spoiler stock, but uhmm im wondering, since the 400 does have a v8, if maybe the dimensions of the hood are bigger as well.

 

nope, same... the cars are pretty much identical except for the motor and wiring...

 

you also get sopilers and the brakes are bigger on the sc400 .i have both and they are practically the same

 

Brakes and Emblems.

I thought the drive shaft was different too?
