I'm hoping this is the right forum for my question. Since the decision is to repair/reinforce the frame and install an aftermarket IFS crossmember or cut it off and swap in a Camaro sub I think this may be the right place. Some background information is that the cracks in the frame resulted from my brother installing a 455 Pontiac in lieu of the 327 that had been there. I don't know if he or the previous owner welded the angle iron into the frame to make motor mounts. At this point, all I am asking is for input on whether any of you would be comfortable straightening the bends and welding up the cracks and using this frame. I figure boxing the frame would help strengthen it as well. I can weld, but I'm not above calling in a pro where it's critical. Background on me is that I was a Fleet Automotive Mechanic for the National Park Service for more than 30 years. I'm far from a master fabricator. My welds aren't always pretty, but they stick together pretty good! I know that this thread is useless without pictures, so I will attach what I have. Thanks in advance for advise!
