Perfect in my book. Many like more of a hot rod engine and put in something bigger. 318's are easy to come by but aren't a whole lot bigger than a 273 in stock form. You can stroke them to 390+ cubes for lots of performance. 340's are getting hard to come by but are a great engine. 360's are easier to find. They were used in many (most) trucks and in basically stock form can be a hand full. It all depends what you want.
