'65 Barracuda 273 engine install from underneath body

Definitely sounds better than going from the top. I've got dollies from Harbor Freight, 1,000 lb capacity, I'm thinking they might work. I like the tip on the threaded rod for guides. Did you have the suspension parts installed to the K Frame? I'm thinking that may complicate the process.
The UCA's with ball joints went on beforehand . The LCA's , tie rods , pitman arm , idler arm , steering arm , steering box , sway bar , spindles , mounts , went on the "K". 383 was fully dressed with carb , water pump , fan . Left off the exhaust . Slipped in great . Calm preparation is key . Mrs. Scampman was tremendous help .
