I moched up a 5.7 with Jeep stainless steel stock SRT exhaust manifolds. I needed to trim the bell of the trans a touch just above the starter, and on an early A the torsion bars were right where those manifolds would exit. I put a rack and pinion and coilover system together along with coilover shocks and springs to make everything fit in the early a. There is a lot of info out there on a 69A to g3 swap, so i am certain there are easier ways to get it done than i did.
