Does anyone make headers for a Oldsmobile 403 that will fit in a 1966 Oldsmobile cutlass?

Can an Oldsmobile 350 engine fit in a 1986 Cutlass Supreme that has a V6 If not whats the biggest engine that will fit?
Yes, an Olds 350 will fit if it's the rear wheel drive Supreme. It is the same basic block as the Olds 307 c.i. engine that came with some Cutlasses. Another option was the Chevy 305 which of course is the same block as a Chevy 350 (another possible option) if you are so inclined. An Olds 307, 330, 350, 403, or even a 455 will fit. The 455 will be tight and will need specific headers for the exhaust. Any Buick, Olds or Pontiac (BOP) will mount to your current transmission. If you go with a Chevy block you will need a adapter plate or a Chevy transmission. v6 and v8 engine mounts are different...so you will also need to change them
