Well , last listing I bought one of the IH truck configured ones, Dan bought 2 of the van ones. Mine has a 1/4 pipe thread at the oil sender, one of Dans does also. all of them have leaked the fuel out of the pump into the valley . The IP likely will need resealed/rebuilt. I am tearing mine down part way to change pan, and other necessary things to make it an F engine.And remove heads to install studs. There is no factory serial number on the block, wouldnt it be cool if it is a new standard block.:0 I will report back with what I find.
Oh and they come on a kick ass channel iron engine cradle.
