I would do some research on using a tall deck. I believe you will have exhaust issues but not certain. You have to use a tall deck distributor which limits your choices, but I believe there is an HEI for that. Seems like the thermostat housing is also unusual on a tall deck. As far as mounts and bellhousing all that is "regular" big block so not that big a deal-same as a usual BB swap. I agree with using the big truck accessories if all you need is an alternator and p/s pump.
