Came across a great deal on a rebuildable engine at a swap meet recently, but can't seem to identify if it is a 4.0 or 4.2 inline 6. I was able to take pictures of the visible codes on the block which I will include, the main ones appear to be:
BV
EF3235444 Cast on the driver's side of the block
A "2" cast on the rear of the block
129 83 Cast toward the front of block on the driver's side
From what I have read online if I had looked at the other side of the block I could have found some more useful numbers, but if anyone knows anything about these codes or can i.d. the engine just by looking at it, I would greatly appreciate it!
