crossover or x-pipe

Yup, and I see many 408's out there, with the RPM air gap, Holley carb, MSD junk blah blah blah that run the same or not much better. And you did it with street tires that are nothing like we have today.

Exactly. It had SS leafs, x-long rear drag shocks, 6 cyl torsion bars, totally worn out front shocks, no sway bars, sub-frame connectors and ran farm and fleet L60's for tires most of the time. It didn't use an H or X pipe either. It would weight transfer hard enough that it hooked on the street too. I won tons of money with that car, but it sure wasn't meant to corner hard.

It's all about the entire package.
