80's factory lightweights?

[old5.0]

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: markjohnson</div><div class="ubbcode-body">In the early '80's, Popular Hot Rodding built an NHRA-legal Super Stock Olds Cutlass from a brand new special order car and if I remember correctly, it may have had some lightweight deletions like that. I wanna say that it may have been called &quot;Project O&quot; or something like that. </div></div>

I've heard stories about some sort of special lightweight G-body Cutlass back then, but I've never been able to nail down any details. I wonder if they would have come on an MSO or a bill of sale only...
