There are ways to adapt a 2nd Gen subframe for the 1st Gen.   Anything can be done with enough time, money and skill.

Either that ^^ or check out Respeed that sell a subframe with rack that will bolt in. You will need to find your own headers thou.

Since Grannies makes a kit for the small block chevy in a sa/fb, the small block mopar will fit.

Call him up, see if its just a engine bracket swap.

Take it from someone doing a Mopar swap into an FC, it can be done, but there is not a lot of support out there and not many people who have completed the swap.  The LA engine in the FB should not be that much different than any other.  Be prepared to make some of your own mounts / adapters if what you buy from Grannies don't fit the way you would like.  Hood clearance will always be an issue with the older carbed small blocks.  Take your time and do a good job on it !
