You kinda said what you want to do with this .... so picking at what's left of my brain, these old straight 8 Buicks had individually poured tin-lead babbit rod bearings which are then fitted to the crankshaft dimensions cylinder by cylinder at least through 1948. This will severely limit how much you can safely add horsepower to these low RPM engines. Then there are those main bearings - reamed to size and fitted to the crankshaft with shims. My thoughts are, fix it up as-is and drive it. 320 cubic inches in that Century wont move it fast, but will have a lot of low end torque. If you have a later version straight 8 that could be installed, i.e. '49-'53, then I think you have some more possibilities with an improved bottom end as well as oiling system. This one, probably looking at a recipe for failure with horsepower modifications. Of course, with a 'nailhead' V8 installed there ............
