I just installed a BB in my 67 camaro. I have roller rockers with tall valve covers and now the wiper motor will not fit as the motor section hits the valve cover. It will fit it I rotate the wiper motor a half turn to the left and drill new mounting holes, however the control arm which connects to the wiper blade arm hit the bottom of inside valley pan. Anyone got any good ideas to help me? I know I can't be the first one to install a BB with tall valve covers in a 67. Any help is greatly appreciated.
