i'm new here but have had several fords in the past.
this is kind of long so bear with me. I've had my ford mustang cobra v-8 for 19 years, i sold this car new to the original owner and nine years later his son traded it back to the dealership where i work.

So i purchased it for my son to drive his final years in high school and college.
It's been sitting around in my garage for about 15 years now and so i was thinking about up-grading the engine.which is the best,a 351 windsor stroked to 427 ? let me know your thoughts.
Thank you
