Want to put the air cleaner off a 426 L2 engine on to a 426 N5 engine. To make it fit (Turbos on each are positioned different) I need to have a 10" length of 4" od dia. pipe. Rather than try and find metal piping that size-could I use a piece of PVC sewer pipe that is about 4" od. This pipe will run from boot on turbo down to a 45 degree elbow that attaches to a metal frame that is just before the air cleaner. Will be at least 3" away from any heat source. Just wondering if I'm losing it thinking this may work. Any thoughts.
