Re: Slightly warped block
You say the block is slightly warped. Did it overheat? If so you have a boat anchor and the rings will never seat properly. There are plenty of 3.8's out there and can be bought for a small sum ,less than trying to machine your engine back to health. Once a block warps or is found out of round don't waste your money trying to save it. The 3.8 is a decent engine and they can be made to run without spending a ton of cash.
