Yes a 455 will fit, but I recommend finding the stock notched valve covers if you want a little extra clearance near the AC unit.
I did a 260 to a 307 swap. Took the 307 from a Buick Riviera and got SCHOOLED on the rebuild. If memory serves I hade to change over the oil filter mount, the exhaust manifolds, a few accessory brackets, the fuel pump...and the kicker....the FLYWHEEL! I say this because I had the whole thing back together and all bolted up, jumped in it for the moment of truth and the starter never touched the flywheel.
ANYWAY I digress. Small block Olds motors are still very easy to find. Look in the local yards in big Olds and Buicks, and the 78-80 Firebirds had an Olds 403 (they are harder to find). Everything will bolt up to stock locations however you may have to reposition a sensor or two depending on what the motor comes out of.
And last of all PLEASE PLEASE I BEG OF YOU....DON'T desicrate your Olds with a Chebby motor!!!
Have Fun!

I have a 1972 350 shortblock, and can get some #8 heads that I would consider delivering or meeting halfway from Fayetteville NC. I'm thinking Richmond would be halfway. HOWEVER I am about to score a running 403 (I keep fingers crossed and HOPE) out of a 1978 Electra...heh heh hehe.
And a TH350 is ample behind a smallblock. Heck my dad runs a metric 200 behind a 455...but never sees over 70MPH.....
