Hi folks. I have a 53 3100. I'm keeping the straight front axle. I will be running a 292 in the 450 hp range, Tremec TKO 600 and Frankland quick change rear end with leaf springs and Bicknell torque arm. I am considering 10" rear tires. I will be driving the wheels off of it and it may wander on to the the drag strip once in a while. I have been ask if I am boxing the frame. Not exactly sure what that entails. Is this something I should do and if so how much and where? Any advice would be appreciated. Thank you in advance.
