So I picked up a '55 Super 56R 2 door hardtop project. It runs and drives and is complete but burns oil and needs work. This site has been a wealth of knowledge with my previous Buicks so I thought I would post something. The '55 been on the trailer since I bought it (a long time) and I'm still trying to decide whether to return to original or update the drivetrain and accessories (A/C for example) to make it more road friendly and reliable. All within a reasonable budget ( I honestly don't know what that is right now). I've read the 425 nailhead seems to be a direct bolt in with updating the trans and driveshaft etc. But if I find a 425 and get it rebuilt, for the same $$ I can rebuild the original 322, which would probably be just as reliable as the 425, just not as powerful. One 322 engine rebuilt quote was around $5,600. I've never tackled an older Buick engine rebuild. This then leads me down the path of putting something newer into it, whether chevy drive train like an LS setup or something a bit different. But that may be a rabbit hole and opens up suspension, brakes, steering questions. Anyone have recommendation for an engine rebuilder in Northern California (I'm about an hour north of San Francisco)? So I can shop around for rebuilding the 322. Anyone had the same dilemma of not knowing which route to take? Any recommendation for 322 engine rebuilding parts or kits? In case I want to tackle this myself.
