Now you don't understand what I'm talking about? WTF?

I don't need to ask/argue anything with you. I questioned the rod length being different, not sure where you got that info. My info reads as stated above, and the tech specs I have for the blocks shows the same deck height. Site your source, please.

specs are in the manual

 

Higgs is correct. Same bore and stroke between a 3.9 and a 4.0 Just a rounding thing. Here's a little history: Rover V8 engine - Wikipedia, the free encyclopedia

 

no one ever questioned that

higgs dug up a dead thread to question a difference pointed out on a 4.0 vs 3.9 and he ended up learning something
