early a with a v-8

Is it just me or are there more of you that feel the early A spindles and small ball joints are just not up to par for a v-8 swap? Don't get me wrong, I know it will work. I have been driving my dart with a wilwood disc kit attached to my original spindles and it seems to be holding up to the 360 and 904. I replaced all the steering components when I dropped in the v-8 minus the torsion bars(slant/6).
Will going to stiffer torsion bars and good shocks be enough for decent handling or should I look for the larger upper and lower a-arms with the larger ball joints. Any suggestions would be a bunch of help!!
