M/T et street ss 275/60r15, 325 whp bbc Nova 4.11 rear, seat time

m/t et street ss 275/60r15, bbc Nova 325 whp 468 cu in, sorting out issues, Ford 9” 4.11 rear w/ clutch posi, tires spun on wheel 3/4”, suspension needs a ton of work, blown r/f shock, air shocks in rear 14 psi, 5 pack leaf springs w/ lake wood slapper bars. Et is decent for the lack of hp, plan on working on a bit of everything. More hp, rebuild this th400 with a manual valve body, replace this jenky b&m shifter, looking at better rear ends rather than fixing this one (this a Ford 9” Bronco housing so 2” off center diff, 28 spline axles, clutch posi), who knows might still be cheaper to shorten this rear to center diff and upgrade to 35 spline axles w/ a true trac diff. Need to fully revamp suspension, need the rear to separate to get more traction/ better 60’, so looking at sliding shackles, rear shock relocation, etc.
