I have a 70 Chevelle with a 582c.i. BBC that made 780 hp & 760 ft. lbs. tq. It is a pump gas motor that will mainly be driven on the street. I am just gathering specs on a new 12-bolt to replace the stock SS one. I talked to Mosier awhile back, they said go with their new 12 bolt housing with a Detroit trutrac diff, 33 spline axles, and their street gears ( 3.90) . My question is , will a Detroit trutrac live in a 12 bolt with the power that I make? I do have a trans brake in my Coan TH400, and will have a Wilson Manifolds 250hp plate. I am thinking to just go with a spool to be safe and live with drive-ability issues( tire wear, turning manners). Is the Mosier complete rear end setup the way to go in your opinions or assemble with Strange & Mark Williams components with another company. I am just looking to do this the most efficient/reliable way possible... Thanks for any info! Jay.
