First Time Out At Fontana Auto Club Dragway

Yup, I have a factory 1969 Dodge Polara 500 convertible with the 383-4bbl. I was wondering if I could get a run just to see what it would do in the 1/4 mile.
No offense intended, But I doubt if that car combo would do 13.49. Probably be in the 15's. You could probably run it. That car is heavy, and they know it.
