I just put a 1972 SBB 350 into my 64 Lesabre. The question is, will the 350s exhaust manifolds hook directly to the 1964s exhaust system? I am asking this question because when I got the car, the motor was missing as well as the front portion (the "Y") of exhaust. Im pretty sure I can find that portion of the exhaust from the Buick Bonery. I dont want to spend $500 for exhaust at this time.
You can do it! Get the y and see what you need to hook together. I have melded many a system together, with your mad skills it will be easy. I am looking forward to seeing your LeSabre 350 together, great project!
