Wisconsin 70 Skylark custom convertible owner. This is my first Buick that I've owned. Needless to say finding parts has been difficult. We have a 350 2bbl with TH350 trans and are wanting to add a 4bbl intake, carb and headers. I also am looking for suggestions on the rear end. Compatible for the 8.2 or less expensive options changing the whole setup out. Any help is greatly appreciated!
