the initial question was about a 350 swap. its probably the cheapest swap because all the factory accessories can be reused. if you swap in an LS series engine or a big block, you have to buy new accesories. all v8 swaps will require headers, motor mounts, etc. all depends what kind of swap you wanna do.
