what parts as such oil pan, valve cover's, dip stick tube fit a 455 ? why am asking is Ive got these chrome parts new for a olds 350 and have dropped in my lap a very nice low miles 455 that am thinking of going with, thanks for anwsering ....jim

Valve covers are all the same (though later ones only use five bolts instead of the normal). The oil pan will physically bolt up, but BBO pans have some additional bulges that the SBO pans do not. I am willing to bet that an aftermaket chrome oil pan is marketed to fit either. The dipstick tube will also fit the BBO but the length will be shorter than normal. The dipstick and tube need to be used as a matched set. In any case, you should start with a complete drain of the oil pan, fill with five new quarts, start the engine briefly, let the oil drain back into the pan for 15 minutes or so, then check the level on the new dipstick. If necessary, just scribe a new line.

thank you joe, one more if I may will my hooker super comp frame headers for the 330 that are on my car now work with the 455?

Not very well. The taller deck height of the BBO will likely cause fitment problems. Usually the collectors will hit the bottom of the firewall or the bellhousing.
