1/4 mile speed and time guess`s

Stock rockers should have been 1.5s It is not the overall dimensions that matter but the length from the push point to the fulcrum and the fulcrum to the other push point. This is a ratio of distance if you do the measurements for both down to the mm and calculate it one will be 1.5:1 and the other will be 1.6:1 Even if the body of the 1.5 rocker is larger. Also the angles of the ends can play a big part of the equation but I cant remember the math to calculate that so dont worry about that part LOL.
