273 or NOT 273?
It’s all about piston choices for any build. What compression you want and is it a street or strip engine. a
A straight six car would benefit from a 273 as an upgrade, but 318’s are much more common.
Haven’t seen any high compression 273 pistons for many years, so if you have a complete 273 just swap all the parts onto a 318 block with many more piston choices at affordable prices.
The 273 closed chamber head is a wonderful casting and any 318 build would be greatly enhanced.
