Selling my extra 671 and intake for an Oldsmobile 324. Will fit 49-56 but has the larger intake ports. The intake was repaired sometime in the past and should be carefully inspected. Supercharger was rebuilt about 5 years ago or so and in the natural finish. It was rebuilt for gas application but I no longer have the info on the rebuilder. I have 2 rebuilt 671s and I only need one. Since I like hex bolts more than Allen, I’m selling this one. It should be cleaned and has 5 years of shelf dust. Although it was covered, it still should be cleaned. $1500 cash when picked up from my shop. I would rather not ship. Located in Willoughby OH 44094. Pm me with any questions. I will give my phone number through pm if you would like to discuss anything. Thanks
