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!
What model MSD? I have a race ready model that was used on my engine before I bought it. I have heard the import MSD dizzys have a bad reputation....at least in my oval track world.
