I would recommend the Roe and as Bone says, go with forged rods and pistons if you can from the start. The comment of "under 700" is direct from Sean Roe. He believes that the engine will live a long life at 5.6 lbs of boost on stock internals. But Bone is correct, if you tear down the engine go with the forged rods and pistons.
As for emissions, there is passing testing and then there is passing emissions...I have the Roe and a full cat delete...in Illinois the emission check consists of a connection to your OBD II port, and if it is not throwing an emissions code you pass. There are lots of ways to be sure that the OBD does not throw a code. There are risks and ethical issues. Lots of people go with high flow cats in place of the OEM models. Some use spacers between the rear sensors and the exhaust flow, some use simulators...some use the least expensive method of strapping the rear 02 sensors to the frame in clean air...
My plan is to see if the truck passes the OBD II test...if it fails for some reason, I will clamp in two high flow cats for the test and pull them after.
So there are lots of emissions issues...and lots of ways to handle them. We even have some counties in Illinois that do not require emissions testing...go figure...and my wife is interested in buying some land to create a bird sanctuary...sooooo, if I can find land in the right county and have a mail box there....hummmmmm...
But go with the Roe! Make sure the VEC III boxes are both placed inside the cab where no water can get to them. If you are going to road race, you should be sure that you have a sump system for your meth injection that has ample capacity (maybe two or three gallons), and that it has baffles that assure that when you are in a turn your meth supply will not be sloshed away from the pick-up point! Hitting the Roe hard without meth can be unhealthy!
