Having driven a high powered high compression car on the street for a few 
years,
I will say that it is not always as much fun as one thinks it might be.

Others have already posted that it depends upon the engine, timing, etc.

In my case, the car's cooling system was marginal for that type of engine,

and
that added to the distress.

I had to run 98 octane at all times, and was running less compression than

this car.

It just wasnt a pleasure at all.

But the suggestion to ask the present owner what is involved is a good
one.
