Just joined this thread sorry for the treasonous username it was my name from gbodyforums.com. i have a 1971 mustang mach 1 h code car with a c4 trans. I bought the car my sophmore yewr of high school and it had a janky 302 in it so we swapped in a 351 windsor out of an old truck because in my area of western north carolina there are VERY few reliable engine shops and i dont have the knowledge to build my own engine. The guy we bought it from had died amd his wife sold us the car for 3000 with no keys. It now four years later has a 351 windsor engine from atk that makes 400 horsepower. I have a set of magnum 500s on the way from cj pony parts.
