Subject: 9" gear changes

o.k. differential experts,

all the "experts" I talk to here in B'ham tell me that you can
exchange ring and pinion gears from a conventional 9" pumpkin with a
limited slip or equal-loc. As long as the carrier bearings are the
same size. i.e. small bearing carrier or large bearing carrier.

But I want the word from the real experts. I've received a reply on a
9" equal-loc with 3.5 gears and want to make sure I can put my
tall(er) gears (2.75) in this pumpkin.

My second question is ...with my calculations given the following data
26.5" tires & 2.75 gears 70 mph = 2440 rpm
26.5" tires & 3.50 gears 65 mph = 3106 rpm

giving a 666 rpm difference

I know it's only 666 rpms but is it worth the trouble to change out
the gears for a 666 rpm drop while cruising. Keep in mind this is a
460/C-6 mildly built combo in a '53 F-100 that is going to be a cruise
machine instead of for racing.

Would the only advantage be gas mileage ? (with a 460 ? yea right !)

Your expertise is anxiously awaited.

Subject: Wiring Books For 302 EFI Transplant.

I am putting a 93, 302 HO and AOD in an 87 Ranger. I found the following books
helpful for installing EFI.
Helm Publications Division, 14310 Hamilton Ave., Highland Park, MI 48203,
1-800-782-4356 sells detailed wiring diagrams for all car models. I bought
'Vacuum and Wiring Diagram' book for the 87 Ranger, one for a 93 Mustang and a
book titled 'Electrical & Vacuum Troubleshooting Manual for the 93 Mustang.'
Ford Motorsport SVO has a book which can be ordered for $5.00, 'Multiport EFI
Engine Management Harness' (Wiring Harness Installation Manual)
If you can find copies of 'Muscle Mustangs and FF.' Nov. 1995, DEC. 1995 and
Jan 1996, there is a series on putting EFI in an older Mustang which is very
helpful. Another good book is on EFI is 'Ford Fuel Injection& Electronic
Engine Control' (How to Understand, Service and Modify) by Charles O. Probst.
There is a site on the net which has a helpful section
titled 'Installing a 5.0'5.8l EFI Engine In an Older Truck' which might be

In regards to the question on the Oil tube
My 292 has only one tube on the left side valve assembly. No oil is coming
out but it has only one. I think this rings us back to the add on oil kit,
what I still have not found anywhere. Also the old manuel shows only one tube.

anyone knwo where to get a good wiring diagram of a 1983 Mercury Cougar.
Just put a 302
and AOD from one into my truck, now I have to get the fuel injection
working. I took the wiring harnesses from the Cougar, but I would like
to eliminate most of the useless wiring.

you should be able to call any svo ford motorsport shop and they will give
you the # of the correct agency in detroit or such as that to aquire the
factory wiring diagram. i did this for an 85 lincoln with 5.0 and aod. i
believe it was $14 .
