These main caps for sale will fit a 318, 340 or a 273 You just need to use the washers or the correct bolts.

Yes they will fit. Would u use them on your 340s? If mopar seemed fit to supply bigger/stronger main caps on the 340 why would want put a weaker part on it. All the rage has been to either install aluminum or billet caps in the last 20 years
