Inliners International Forums General Discussion Blown and Injected Truck or late model turbo on inline

It is a flat head L8 so I can only push so much air through it. I would think truck (diesel) for the operating RPM being somewhat similar (around 4500 rpm)but without the volume of exhaust of a 7.4 diesel, on the flip side smaller car engine with a turbo I don't have the RPM but should with a 327 have a decent volume of exhaust to spin the turbo so which is better?
