Thanks for all the info, Kerry.
I have a fair amount of knowledge on the car and 442s in general, and have been doing a lot of research recently knowing that I would be buying the car from my buddy. I've lost count of how many olds shows and trips to Carlisle I've taken over the years for this car and for another friend who has a '67 442. I have no plans to deviate from an Oldsmobile powertrain at this point, so I may eventually look into adding a correct 400 cu in engine to the mix. The Cutlass S rear end is another weak point with it only being a 10 bolt and (from what I remember) this one was equipped with and open 2.73 rear end. That may need to change pretty soon too.
I'm now really starting to research more on the suspension portion of the car as well. The bad thing about this frame is that we had to add some patches back when we did the restoration 20 years ago, and if any real HP will be added, the frame will need to be really worked on or replaced. I've already began searches for A body frames. You can buy box kits for hardtop frames for fairly cheap, so that gives me more options in finding one at a decent price.
Really looking forward to just spending some time on the car, freshening it up and driving her this summer.
