Have a pair of 66/67 427 Fairlane 31-spline axles that I just swapped out of my street car for some aftermarket axles.  I've searched all the usual areas on-line and haven't found a recent benchmark for any FoMoCo factory HP axles.  Would seem to be in a similar range to Mustang/Torino CJ axles.

What have y'all been seeing out there recently for axle prices?

Thanks in advance

I have an Addco 715 bar on two of my 66 Fairlanes with FEs

Would second that on the 3" main with 2-1/2" tailpipes.  I have 3-1/2" pipes from my headers to the Dr. Gas X, then 3" to a Spintech resonator (added later), to 3" Dynomax Ultraflows, then 2-1/2" over the axle and out the back.  Sounds wicked when thrashing it, very tolerable at idle and cruise.

Car has run low 11's with that setup on drag radials.

The engine should make a good seat-of-the-pants impression from 3,000-5,200 or so revs.  You may notice a loss of torque off idle and when lugging the engine at low revs.  If it were my car, it would have already been swapped.

A short input shaft kit, new clutch disc, new slip yoke.

Brent - are you offering short input shaft kits?  Might be interested in swapping out the TKO600 for one if I could use my current clutch/bell/driveshaft setup.

What a great installation!  Does the ECU control the transmission as well as the engine? 

Stories, eh?

So, many years ago, I was out late at night wiith a group of other car guys match racing at Martin Tractor in Topeka KS.  I had my 66 Fairlane GT, 12:1 390 solid lifters, toploader, 4.57 gears, G60-14 tires. 

I'm getting ready to make run against a guy I should easily beat and make $50, when I whack the throttle hard in first gear to clean the tires, stab the clutch to grab second gear, when the clutch rod drops out of the clutch fork and the engine dies.  Mere seconds later, we hear the sirens of the incoming fuzz.

Everyone else tears out of there, except me, with an inoperable clutch.  I think quick, jam it into second, crank the starter, and head off down the access road at 6000rpm, knowing that, if I stop, the car will die again.  Car wouldn't shift into third, so I somehow managed to make it all the way back home (ten miles) turning 6,000rpm and going about 35mph (or so it seemed).

No damage, no ticket, but a distinct memory

A 15x8 wheel on a 66 Fairlane needs 4-3/4" backspacing with drum brakes.  Disc brakes are a bit thicker on the hat and will be a 5" backspacing to center between the spring and the wheel lip.
