During the time until you order, and then receive, your engines be sure to read, read, read these threads. And then read some more.
Click on any thread headline that looks interesting and stick with it until you're finished or you lose interest. Then click on another one.
In no time you'll have a notion of what engine/drive train you want plus you'll pick up very precious tips and tricks. They'll be worth their weight in gold as far as preventing you from making errors that stop you in your tracks.
Lots of good info to be found here plus helpful folks who are rooting for you.
