273 rings available?

I do not advise buying Egge pistons especially for the 273 if your buying the 10.5 Hipo Repro pistons , as i had a conversation with them 2 months ago about a 273 that was in my shop and they could not tell me the Dome CC's , Compression Height and many other aspects you would need to know to spec cylinder heads and what not to build a proper engine, and to top it all off its still so under powered even compared to other mopar engines of the time. there really isint much out there for the 273 to build it to make more the 250hp N/A your better off using a LA small block and actually have a selection and all your external 273 parts will bolt right up
