I could be wrong but aren't the bellhousing crossmembers in different locations, v8 crossmember sits about 3" forward of the location for the 6 cyl. My truck came with a v6/4 speed originally and I swapped to a 350 and now my engine sits about 3" farther back than a stock equipped small block would. To get my engine mounted up I left the bellhousing crossmember where it was and I got some engine stands off of a 250 I6. So if you swap for the v8 in your truck you will be fine, you just need some 250 I6 stands and have to either get a 4x4 fan shroud or convert to electric fan. For the other truck though It will make the engine sit about 3" forward of where it should, which may cause radiator interference and I'm not sure what you would do about motor stands. Here is a picture of how my 350 sits in my engine bay, you can tell its further back because of the big gap between the water pump and the rad and also how close the dizzy is to the firewall.




Hope this helps.
