I thought having a CSX number on my engine would be cool (whoop-dee-doo), but ~150 pounds less weight on the front end does make a significant difference in handling.
BTW, I have a *really* good deal on a 390FE, *almost* a complete engine (I think it came off a '69 Mustang) for *free*! The downside is the gouge in the cylinder where the wrist pin moved a little after its retainer disappeared.
But if you have access to a machine shop [that a relative who owes you owns], it might be worth doing a cheap rebuild. If you live in the Bay Area, just come on over and you can haul it away.
