Six cylinder torsion bars with big block

I have the slant bars on my cuda with 440/glide, no inner fenders, batteries in the trunk, alum heads/intake etc etc. I am putting the car on the street after being a track car for the last 20 plus years, I am sure that during that time it has sat on the bars/springs at least 98% of the time since back when new in 1967, they are old and Im sure fairly dead by now. I have put a front sway bar on mainly cause I got a good deal on it and to help stabalize the front for street and I will NOT be driving crazy on the street, too old for all that fancy road race driving. Since these bars are antiques I am going to go ahead and change them out but instead of bigger bars I am going with coil overs, not for any type performance gain but rather just because I can and will look cool.
For my type of street driving Im sure a decent shape set of slant 6 bars would be just fine.
