Dude, the Picco .26 is the perfect way to get great power without much mod. All of your stock stuff will bolt onto it, ie; flywheel, clutch, clutchbell, header, EZ start, etc. All you need is a $20 Ofna mount and you're in business. Great motor, especially for the price and ease of installation. I ran the OS 28XZ in my Truggy and downgraded because it was too much for good handling. I suppose if all you do is go in a straight line and don't care about your truck, the 28 would be fine. As for the Revo driveline holding up to the power. You do not need metal center driveline to run the picco I raced mine competitively with the stock drivetrain and it did just fine.
