I really appreciate everyone's input on this thread. We are excited to get started upgrading and building this van out for our summer travels. I don't think a new engine or drivetrain is in our budget, so we'll be doing the best we can to upgrade or just get new parts to make sure everything is running in tip top shape for the best MPGs we can get with our current setup. That being said, let me post a list so you all know and I can hold myself (and remember) everything that I plan on doing to the van. We're picking it back up this coming Tuesday.
- Upgrade battery cable to 2g wires. (What other cables should be replaced with new 2g wire w/ kevlar sleeves?)
- Upgrade to 1993 or newer starter for ford 460 application (anyone have link or vehicle to recommend?)
- Possible edelbrock or similiar carb upgrade and tune
- Cigarette port/12v socket fix (I plan to go through the entire fuse box under drivers side and dremel out all the fuse connections, a lot of them are rusty and I assume some things aren't getting good connection)
- Install new fuel filter, who knows the last time it was changed. (link to writeup on this anyone?)
- Instrument cluster dash lights need fixing (I'm hoping this is part of the fuse issues, we'll see if they come back on after all the rusty metal connections are dremel'd back to metal.)
- The rear red running lights aren't working (again hoping a fuse issue and not a wiring issue here. anyone have this issue before?)
- The temperature gauge isn't working. Everything else does. Do I need a new temperature sending unit possibly?
Really appreciate everyone's input and suggestions as we begin to work on the van. Please say what you feel. I have only moderate mechanic skills with a decent set of tools. Most things I will attempt but tough stuff may be going to a mechanic. I will keep everyone updated on the status of things!
I don't know what your budget is but there are fuel injection conversions for the engine you have. Might be worth some research to see if they are worth the cost. If you plan to head into the mountains, a fuel injected solution may be something to consider (to optimize your air:fuel mixture as you change altitude).
With any vehicle or piece of power equipment I obtain, I always change out all filters and fluids for the best replacements that I can buy (typically Mobil1 fluids and high quality filters - NOT FRAM!). I consider it cheap insurance and you have a starting point to track your maintenance. Don't assume the previous owner used the correct parts/fluids or added the correct volumes of fluid. So if you haven't done it, plan on changing your engine oil, tranny fluid, diff. fluids, brake fluids, air filter, fuel filter, etc.
Sounds like you need a multimeter and learn how to use it to track down your electrical issues. My next question is why are all the fuse contacts so rusty? Was this van in a humid environment or has water physically entered the fuse box (as in, the van was flooded)?
Regarding the engine heat, you could look into adding vents to the hood (

I would also start assembling a mobile repair kit that you keep in the van. Sounds like you have a lot of electrical issues so parts to fix or bypass bad connections might be handy.
Keeping your speeds low will help on the MPGs. Your van has the aerodynamics of a barn; time to take it easy and run 55-60 MPH. You are pushing a lot of air and there is no way around it. I get close to 20 MPG running at 60 MPH in my van. You can try things like these:
