GM used V-8s in a number of cars before 1955, so I'm not sure what you mean by keeping the spirit of 55.

If I remember correctly the 55 Pontiac motor is the same family as the 389 and 455. I'd consider replacing your current motor with one of the newer motors from that group.

Just my two cents...
