Better call up every salvage yard in your state and ask them if they have any engines out of a 88-89 RWD A/T 2.0L Mitsubishi/Dodge truck. Also ask if they have any engines out of a 86-87 RWD A/T 2.0L Mitsubishi/Dodge truck, but they must measure the bottom bellhousing bolts and make sure they are 13.25" across.
I know of a complete motor here in New Zealand i was offered, wide block from a starion. Not that it helps you much.
No idea what would be involved with sending a motor over to the US.
He wanted $200NZ for the complete engine.
He might be willing to sell the block seperate though, never know your luck.
Would really depend on wether the guy could be bothered sending it overseas also though too.
