I took my 100,000 mile HP273 apart years ago . It had little ridge and very little taper. Mopar small blocks are high nickle blocks and don't wear much. The crank in that 273 is forged and not cast and don't wear much either. They're pretty tough although grinding and polishing doesn't cost a bundle. It really depends what you want out of the engine and how much it will cost you to buy. Heck the valve covers, intake, carb, and dual point all have value.
