i kinda have to agree with hokie, your fastes and cheapest bet might be to find a Chevy 350 as they are abundanty and cheap. just find a used one and throw it in. When yuo get a little older and a little cash, rebuild that Pontiac motor and put it back in. Sounds like a lot of good parts in it already!!
