Swap or rebuild?

5.9 are the best bang for the buck the 300hp create engine is a stock 5.9 dressed like LA with a 4bbl intake and dynoed 320hp with headers, why does everyone think you have to do everything at once, do up grades as you can afford them, $1000 ain't gonna go far a good exhaust will eat most of that but start there, then maybe intake and carb but get one that bolts on to magnum and LA engines, do ignition, gears etc.. then when your ready do the 5.9 swap and you haven't wasted anything except gaskets.
