So should I go with the full length or the block huggers? My truck was a 307 v8 truck from the factory and has a set of cracked ram horn manifolds on it now... I want to keep the 3 on the tree for now... and am wondering about shifter and clutch problems... so the block huggers look good to stay away from that but am not sure about the full lengths, but full lengths are easir to set up an exhaust on... I am not sure here.... HELP
