    I dig it. I've had it in my mind to make a BBB sleeper out of my '85 coupe for a while now. Be curious to know how the motor fits when you get that far......

    Good luck

    Curious to know if you got the 455 in and what you needed to do to go from the 307 Olds mounts to the BBB?

    I'd be interested to know how that 455 fit too...is there even enough room?
    I'd love to be able to stuff in a BBB into a late 90s Roadmaster...and then "modernize" it with fuel injection and variable timing on electronic ignition, it would be interesting to see what it would do once "maximized" like the 3800 was.
    So this thread has me interested; an 80s vintage Park Avenue would also be a consideration, and might be easier to build.

    Have not got the 455 in the Lesabre yet..
    Its on my engine stand .....
    Been trying to start it...
    Was converted to HEI when it was in the parts car....but they never got it started..
    Just picked a new coil and module and cap.
    Gonna keep trying the rest of the week.
    Ready to hear it roar to life..
    Nothing special, just a stone stock "72" 455.
    If your intrested I do have a kind of a Guideline to installing a Buick 455 in a 80s B or G Body , same process applies to both.

    Interested in seeing the pictures and the parts required to fit one in; - Does the saddle allow for a 455 or does that have to be modified too? I suppose drilling in new mounts isn't that much of a challenge, provided the motor lines up right and isn't up too high or crooked.
    Looks like an interesting project, and as I said, I'm toying with the idea of modding out a mid-nineties Roadie with a 455...I'd love to modernize one and maximize it.

    Thanks for the update. I would love to see any kind of guideline you would be willing to share. Would like to make this my winter project
