Getting ready to swap a 5.7 into my 73 Dart Swinger

It seem minuscule so I'm moving forward I tested of everything with the one in 3/8 pipe for the header just made two small little Cuts in it send them down made a rough angle to see if I could pass in between the steering and the the engine mount I can do it but I'm also going to use the one in 5/8 tube 304 stainless steel drove out of my way to a metal shop that told me they had it they ended up not having it
I finally see why everyone's so wound up about motor mounts, TTI, spools, steering box... My spooles were pretty shot. Not surprising as the entire bottom looked like they used the car as a stump-jumper. 1 MM was fairly cracked and the other was welded at the factory, late on a Friday before a holiday with a hangover. I just wacked em both out. Put my MM where I wanted them. Y'all got some real battles going on :-)
