does anyone know is you can get a tunnel extension for a 154 to a 174 i and would i be able to use new rails to extend to accomadate the new track or would i need a 163 skid and ice age rails. i would like to get the biggest track i can and am putting in 7 tooth avid drivers. and would a BB have enough power to spin a 174? thanks for any response
