I always thought the advantage was the 6 spd chevy uses. What is the gear ratio in the 6spd LS1? I drove a Sentra SER specv with a 6spd and it felt like just that, 6 forward gears. When I shifted it into 6th it didnt feel like a OD gear. What im trying to say, would the Fox bodied car hold up after 3rd gear if it had a LS1 tranny?
