with a narrowed 9" houseing and rear brace, and 4 link. when is it nessary to go to a chromoly after market houseing. to what hp will it be safe to?

bjuice

assuming you have
good axles 35 to 40 spline ( have seen 33 spline live)

a good aftermarket 3rd member with billet caps ( pull thru bolts)

set the car up with the 4 link with minimum body roll

also depending on how much you narrowed the housing..this promotes strength in itself


i have seen them run well over 1,000 hp..hooking with 1.12-1.13 60 ft's
