BIG BEND OPEN ROAD RACE

A few years ago I remember reading in the local Mustangs Clubs newsletter the story of one of the members who took his 427 powered Mustang or GT-40, (can't remember which) down there and promptly blew the engine in spectacular fashion.
Straight-a-ways that are miles long really test the engine & overall stability. What fun !
