Real Big Big block question..
Exhaust is a huge issue. You'll probably have to have headers custom made for the car, and they will most likely have to come through the wheelwell because there won't be much room between the block and subframe.
Hood clearance may be a problem...you might have to run a cowl hood in order to fit an aircleaner in.
Get an aftermarket radiator and dual electric fans. I'd be surprised if the stock cooling system could keep up with a big block's heat production.
Otherwise, it shouldn't be that difficult. You may have to do a little fabbing for motor and tranny mounts, but you won't have to cut any chunks out of the firewall or anything. The car is gonna be VERY frontheavy when you're done...better plan on a big brake upgrade soon after the swap.
