Re: 73' Olds 455.

Don't sell the 455 short on mpg. They were known to achieve 18-20 mpg in a stock big olds 98 with a high geared rear ratio in the 2.73 to 3.07 range.
But since you are looking to sell your engine I suggest a compression test as said plus an oil pressure test. These two items will help determine a solid engine. Also include a running video if possible. Everyone would like to hear an engine run before purchasing.
