Need A Recipe For A 273 Rebuild

Personally I would just build a larger motor. Even going to a 318 will be a big plus.

If I were to build a early a body I would start with a 360, nice set of heads, a small solid cam in the 245 @ .050" range, M1 single plane intake, Holley 750 and a set of headers. Paint it all red, Add a set of 273 commando valve covers and air cleaner and tell every one its a 273. Whos going to really know ?

Back it up with a 4 speed and 4.10s for good measure.
