And this time its not being built for the street. Im going to be running an open 3.5" downpipe and an open 1.5" wastegate. Boost will be in the 20# range on E85. We'll start looking at building an intake if we pop the stocker. I still dont think cams are needed to make 700-800 rwhp on the 3.7. Maybe if your looking for 1000rwhp but your getting close to the limits of the stock block at those levels.
