I posted earlier about an OMC Drive with a Chev 3.8 crankcase full of water. Still havn't found out if I have a cracked block or leaking intake, but found a good deal on a Chev 4.3 that is hard to pass up. They tell me that they share the same block, is this true? The 4.3 comes intact except for the exhaust manifolds, will the 3.8 manifolds bolt up to the 4.3. Also will the 4.3 bolt up to the drive without any problems, I know, lots of questions, but I know someone here will have the answer.
