Re: LS Swap Dually Questions - First Timer

Speedo Converter Box (Maybe)
Dakota Digital gauges (stimulus check haha)

Questions:
1) What oil pan should I run, I do plan to lower the truck after the swap is done and running reliably for a while? Holy-302-2?

2)Will I need to change out my cross member? If I recall correctly the dually has plenty of room.

3) Can I run my 85 Fuel Tank (brand new) with the 87 sending unit and pump? Or should I just order a 87 baffled tank?
I sent my harness out to be reworked. There are lots of people who do it online. You can buy a new harness for your on Amazon now too. After wiring mine up I think I'll do my own harness next time. It doesnt have as much to it as I initially thought.

Since you are staying stock you can send your computer out to have the VATS/rear O2 sensors removed. Again there are tons of people who can do it online.

I managed to get all my stock gauges to work (the speedo took a bit more work). Check out all the threads by aggie91 or LS1nova. They both have write ups on gauges and getting them to work.

For your specific questions-

I ran an Fbody pan. They are more expensive but I moved my engine down and back and wanted the most clearance possible. Lots of people use the muscle car pan since they are cheaper and a bit shorter.

Not sure which crossmember you are referring to but both the front and the trans crossmember can be used.

You could probably get away with the 85 tank as long as you keep the tank over 1/4 full. I would spend the extra few bucks and get the proper baffled tank.
