Well i think i found the problem

Pulled the engine out (actually a bunch of badass friends did since im at school right now and the car is 100 miles away) and the oil drained consist of about a third of water/coolant. This is on a 95 z28 with 116000 miles. Trying to figure out the most cost efficient way of getting it running again. Im pretty sure since there are so many miles on it and not knowing how many miles of those were with water in the oil that the bottom end is toast. Ive seen a few short blocks on here for pretty cheap..............What would you do. would you try salvaging anything or would it be cheaper to buy someones rebuild???..Funds are very limited
THanks alot for the help
