Stroking a 318 to a 390

Dump truck
Yeah, it's pretty close, rolling weight is around 4100 pounds. We've had a bad MSD distributor rear it's head but we're back on track again, about to finalize the tune and test drive it. Three inch pipes with a Dynomax X-flow are going together for that task, but break in worked out to the good. It sure sounds like a bear with open headers on it!
