as im still new to cars and specifically buicks i had a few questions for ya guys concering my 72 lesabre custom it has the 350-4 which starting in the next month or so will be my daily driver 1.posi is it worth it and where could i find one or a swap that would fit it 2.i need a new exhaust system was thinking flow master so is there a good set up from flow master that would provide a nice lil rumble not much but not to little. ( i like the sound but dont want it to be ridiculas also want it to be street legal) 3. also people talkin bout the bucket seat and dash swap from a riviara fitting the lesabre does the riviara have to be the same year as the lesabre and does anything else swap out easily between the tworay: 4. anything else that could make my old car perform a lil better and look a lil better under the hood :TU: thanks for reading
Is a posi worth the trouble? Yes, if you plan on drag racing. Otherwise, I wouldn't worry about it. The 72 LeSabre with a 350 has an 8.5 rear, which you can buy aftermarket posi units for. The big block cars have a 9 3/8 rear, and are very difficult to find posi units for them. Walker Dynomax mufflers are a popular choice for a nice rumble, not too loud. I have a set on my 71, and had a set on my 71 convertible. I don't know anything about a bucket seat swap from a Riviera, but it makes sense that it would fit. The dashboard configurations are exactly the same. There are several low budget things you can do to your car to wake it up. Ignition recurve, dual exhaust come to mind. This board is absolutely packed full of good information. Start reading!:beer
