Thread: Olds 455 exhaust manifolds

  1. #1
    I need a set of Olds 455 exhaust manifolds. Headers are not an option. I would like to find a set of early model ones without the crossover but at this point I will consider anything. Thanks

    Be careful with used Olds logs. The center area with the 2 exhaust ports together is prone to overheat, cracking, and warpage. Used ones are many times taken off for a reason and end up at the swap meet or on ebay for sale. Just check em out throughly before buying any.

    no problem. sorry i couldnt help.
    rex. your right about the shared center ports getting hot and possibly warping. i have never ran these as i allready had a set on the boat. i just bought a complete 455 that someone was doing the swap to a chevy. but they look pretty good. i wont be needing them, so i thought if i could help a brotha out. you know?

    Back in the days when Olds were popular we sold lots of replacement logs because of center burnout. Not that many left around any more I guess.
