Tuning a 948cc Engine

[wildwoods]

Hi All

First post here. I have a 1958 Morris Minor with a 948cc engine. I am looking to tune it and am wondering the best way to go or would it be better to install a 1275cc and tune that? I am looking at using supercharge to give the engine a real boost.

My aim is to be able to climb hills quicker than 30mph!

Thanks for the help.
