A 8 inch converter is suppose to have more torque multiplication in 1st gear than a 9 or 10 inch does shruggy
I read a magazine article on this a long, long time ago saying that the 8 inch Opel based race converters had around a 3.25 to 1 ratio compared to the 9 and 10 inch converters which had closer to 2.5 ratio in them confused shruggy
It did NOT mention how long that effect lasted, 3 feet or 160 feet work
