I have two big block chevys (1968 2"s forward + 1970 stock location). If your going to make the swap it's easier to move the engine 2"s forward. You can install a 700R behind and the lengthen your transfer case shaft. The advantages are it's easier to reach transmission bolts, more room for valve covers, and HEI fits easier. Stock location on every truck will be a little different but you can put a 454 in the same place as your previous motor. Modifications are miner to make it work. The added weight will make the truck bounce more in front so I would suggest installing a rear gas tank to help balance the truck back out.
