since i've gotten by '07 gt, i haven't paid much attention at all to my 96. Well, after racking up 23,000 miles my first year driving the 07, i decided i wanted to put some money into the 96 to make it my DD. It has about 150,000 miles on it, and it runs like crap.(cracked intake manifold) I'm looking to spend about $3,000 on it to get it running strong. What should i do? Rebuild the engine and put PI stuff in it? Just switch out PI stuff?(would take care of cracked manifold) Or should I do a PI engine swap? Which one would be best and cheapest. I don't have anymore than $3,000, so please keep suggestions in that price range. If i have enough left over i will get 4:10's. Local shop has a special going for $375 right now.
