I've always wondered about dropping an Olds 455 in place of a 403. I'm sure it can be done, the shaker is the only "unknown". I see you have at least one 403 car. I've driven and ridden them. Nothing wrong with the Olds engine, to me.

my brother put a 70 w30 in a 79 403 ta he had back years ago.

I remember seeing one 79 TA....with a 70 455 olds in it....years ago

From what I recall...the original shaker was on it....and the hood closed....but was a tight/close fit...

The deck height on a big block Olds is 1.3" taller than a small block.
