What would be the edge limit for HP/TQ using the stock axles in the 8 3/4" rear?
Currently I have a 489 case (West Coast Diff.) with only @ 3500 miles on it if memory serves me right it has the 1 7/8 pinion which they highly recommended. SS springs, otherwise the housing is the original unit drum to drum.
My Duster is a street driven car/occasional track under 370 rwhp on street tires. assuming my setup is more than adequate.
I have been offered to use a friends M/T mounted street slicks but I've been hesitant thinking about breaking an axle with the additional traction.
Planning on finally getting the heads ported and a roller cam this winter which should get me into the 480-490 crank HP range, and I'm sure still under 400 rwhp due to parasitic loss (trans)
Stock 8 3/4 axles an issue here?? Or no concerns
