That is pretty much want I is the ram air cover. I'll have to take a closer look. In the century I have tons of room to mess around with so it might be possible. A 3500 top swap would be cool, but on this car. I'd just do the 3400 top swap and call it a day. I don't know how long I will be keeping this car.
I know that feeling. The 3400 top swap would be cool though. You should try to find the 3400 plastic engine cover. It would clean up the looks of the engine bay a lot, and it would confuse anyone who looks under the hood haha.
