alright today I finally got my MM FLSBCs in. I was in a hurry and just borrowing a 220 mig. I got the front of them perfectly flush with the front subframes...The rear had a decent size gap but I still welded them in and closed the gap by welding it closed( maybe 3/8 of gap. Do you guys think as long as I have a good strong weld I shouldnt have any problems? (Not using a torque arm or anything).
