Ford 8" upgrades

Postby SLCK64 » Mon Jul 17, 2017 9:54 am

Looking to go with a 3.80 gear in the 8".

What are you guys running for limited slips/bearings and such? Will be running a Top-loader wide ratio trans and a 302 or a massaged 260, depends on what I hear back about the rules.

I plan to run this at the Uncle Sam's Pie Eating Contest at Byron Dragway next June. It is put on by the Meltdown Drags guys and will feature cars of pre-66 years running by 1966 NHRA rule book on pie-crust slicks only. No burn outs or dry hops, just pull up to the tree, wait for it to drop and go. Even more traditional/vintage than what the Meltdown Drags are I gathered from what they were saying this weekend.

Can you run a spool?
66 Cyclone GT; 245/60R15's on 15x8's and 215/70R15's on 15x7 Magnum's.
There's nothing like the sound of a pushrod V8 singing at the top of her lung's.

I used a Eaton Detroit Tru-Trac and 3.80 gears for my 64 Falcon track car.
Haven't run it yet though.

According to the '66 NHRA rule book in the "Stock" classes "Ratchet type(limited slip) type rear ends are accepted. Quick change or locked-spider differential rear ends are not permitted."

Plus I will be driving this on the street from time to time so I dont want to lock the rear end.

Thanks for the replies so far!

Another thing I just remembered, I have an early 8", so has the weaker case. Since this will see strip use, I would hate for the case to crack while Im having fun.

I have seen these on Ebay for a few years, and really for the money, I dont think I can go wrong.

All good reviews and I can get 3.80s installed, have him do a billet yolk(for $75 extra), and I think that will be a nice bullet proof setup for my 300hp 302. He can even do a tru-trac for $225 extra if I want. Heck I could get some $$ off if I can find an extra rib case at a swap meet and send it back.


Anyone know of anyone who has used this ebay seller before? Or know TJ?

I bought an 8" setup from him for a 'Stang about 6-years ago. Definitely knows his stuff and the chunk was very nice. Lot of coin to throw at an 8" though...especially with any upgrades. I'd take the base deal and roll!! Meat for pinion support is the most common POF and none of that stuff is gonna help that. :D

I think it'll be fine! If I hadn't of had 9" noggin-crazy going on I could have saved a big PITA (or two) moving forward!

I believe there's a thread on TFFN where a dude did everything under the sun to try to beef up his 8 for drag racing.
I think he tore the pinion out of it once or twice...I forget the outcome.

Well the plus side to the drag racing I am going to be doing is with pie crust slicks. No smokey burn out and such to get them real sticky. In the 60s they just rolled up to the line and went. So the forces wont be as crazy as if I went with some M/T ET slicks say.

I am gonna email that place and see what he thinks. I suppose if I am gonna spend the money spend a bit more and get a whole 9" with some decent axles too.

Ill let you know what I find out.

I kind of hate to say it, but the best mod for the Ford 8" is an 8.8" LOL. The axles out of a '95-'03 Explorer are the same width and bolt pattern as the Comet's 8". They also have disc brakes and come in your choice of 3.08, 3.27, 3.31, 3.55, 3.73 or 4.10 and limited slip or open. I'd also recommend a 31 spline axle over a 28 spline as they're supposed to be about 34% stronger.
Cheers!
