I basically want a sub 3000 pound 66 wagon with the best overall handling and braking using (primarily )OEM-sourced parts and assuming 15" Max wheels (15 x 8 cop wheels most likely). Only exception may be the rear brake discs which I'll probably do a Dr diff kit.

Probably 11.75" Cordoba rotors, 340 A body .870 torsion bars (or slightly larger since I've got some fatter tires), XHD (340) springs in back with bolt on swaybars.

This is not gonna be a drag car, I want this one to drive and drive often. 5500 max RPM, 10:1 and "only" about 525 hp with crushing torque curve all through the powerband. 3.23 or 3.55 gears, shift kit. Motor is already sorted and ready to go.

So basically I want a slightly improved police type ride in a ~1000 pound lighter and better weight distributed package.
