If I wanted to build a mid 12, low 13 second 5.0L stang what would you suggest I do to get there.... like which parts should I change, should I bore, change the stroke? Supercharger it....
I'm just curious with people with a 12-13 second setup and what they have done to it. I'll be figuring I'll be buying a stock 5.0L if my parents make me sell my stang now and going from there. This probably won't happen tell next summer at the earliest if it happens at all but I am currious ahead of time. I would prefer to do it all motor aswell.
Aswell I want it to be a street car too... so I'd probably stick to 3.73's.

Thanks,
