I'm doing up a stroker motor, and I'm keeping the original 318 torsion bars. If you don't already have one, get a front sway bar, a nice thick one, it'll take some of the grunt the bigger bars would handle, yet overall give you a better ride quality, plus it'll handle a lot better. If you already have a bar, great, you'll have the tabs on the control arms, just upgrade size if you want a little more firmness in the front.

My car didn't have the tabs, so I made some and welded them up. Added the Addco 1 1/8" bar.

All my control arm bushings I removed myself (wow) and had a shop install them. everything else is simple given a few tools you'll need.

Torsion bars are easy to remove just by unfastening lower control arm, and prying it back, the t-bar comes un-done from the frame, and you can wiggle the control arm free of the bar.

Good luck.
