Hollowing cats? E fans? Synthetic fluids? What else?

Cats really nothing unless they are clogged, bump timing a couple of degrees, e-fan about $120. for fan\temp control, synthetics will find all leaks, I use Havoline 10-40 and still get about 6000 out of it, you might get a little increase plus a little mileage, the best thing to do is get a good exhaust.
Heres the best bang for the money: http://fullsizebronco.com/forum/show...ht=timing+bump During a discussion w/ a Pertronix Tech regarding an ignition box addition to my current Ignition system set up (60K HV coil/.46 ohm// brass cap & rotor// MSD superconductor 8.5 wires// stock Motorcraft cooper core @ .54 sidegap) he suggested I save my money by forgoing the purchase of a box. He said the reason was, there would be no unburned fuel for the box to capitalize on. However with a stock gap plug, where fuel ignition depends on spark intensity & duration rather than my set up, which relies on Spark Kernel exposure (Producing less residual by-product heat when doing so), the box would be beneficial. Here's a link about sidegapping plugs: http://www.performanceunlimited.com/...degapping.html Stock gap for my 87'302 is .044. I also get 17/23 MPG.

Higher spark output means cleaner burn and better performance and BETTER MPG....
they work the best at idle and lower RPMS where the fuel is the richest...it can only help not hurt...but it does cost...

but for the money I would rather have a TFI with a long DwellBut I do agree as far as the MPG goes.
