454 swap into a half ton sub 4l60 living?

[Moofus02]

now hold on a minute here in the first post it says that the 454 has a nv4500 while I have never seen a manual in a gmt400 suburban and as far as I know none ever left the factory with one dose not mean that some things happened to get it done or maybe it was swaped in at some point but that would also be a great option imho

If you have more 5.7's you can swap in, they make the most sense.

The easiest, fastest, cheapest swap, is always back with the same thing it has now.

well the swap could be done but the drive shafts may not fit would need to have the rear one shortened the front may fit good chance of needing combination u joints
