Thanks, I knew that the block was the same up to about 1985 or so Gen 1, then they went metric and made a lot of other changes. I know that will have to match up pulleys and stuff after get the swap done as it has a hashed up power steering. They cut up the frame and welded in some pieces for the steering box that have no idea what it is. If ever goes bad may take a torch to take it out. I think my pulleys will be ok as is on the 350, but never know till is done. It came with an alternator and bracket for it and a power steering pulley, if it matches up. The balancers are different as well as long vs short water pump. Attached a couple pictures of the steering box. ( I think)
