273 or NOT 273?

Thought about it but seeing my car is a 67 , it would seem fitting that I build a 273 lol. I guess I'm really the only one who understands but I think it's more the fact that my friend had a 289 mustang, 4 speed car with 12.5/1 revving screamer. The fact that the first number was a 2 and not a 3 was so impressive to me , even though it's basically the same engine. Nor sure if it makes sense lol.
I get it my name is 273 because when I joined up my goal was to build a 7000-7500 rpm 273 Time Attack 65 Cuda, but I realized Time Attack was above my pay graded :) sold that and bought a running, driving 68 Valiant Signet with 380hp crate 5.9l but I still thinking of finding a 273 to play around with, was thinking of running the magnum crate top end on a 273 short block and see what she would do in the 1/4 mile :)
