Thread: 3.5 to 4.0 Do I need a new sump?

I am guessing I already know the answer to this question.

I am swapping out a tired old 3.5 to a revitalized 4.0. I have noted the on the 3.5 the dip stick goes in through the block, just near the engine number stamp.

On the 4.0 there is no provision for this, so do I need to get my hands on a sump pan from a 4.0/4.6 where I am guessing the dip stick goes straight into the sump?

Maybe other later 3.5 and 3.9 had the same dipstick into sump set up and it might wider the chances of getting a different sump cheaply.

Thanks in advance,
