With the V6 for me they suggest 5", I'm thinkin that's going to be way to tall for my liking. You're putting a 4 banger back in and taking out the deisel, yes? I've read I could also use a T100 oil pan and pickup, I guess it's shaped differently then the V6 and will be out of the way of the diff.
Maybe I should look in to that so I can stay @ 4". I want it to match my cruizer coiled rear so I don't have to do anything there yet.
