Default Engine, Tranny, and Rear Axle codes

This is something I've been working on for a few weeks, some people can't afford a Hayne's manual or Chilton's(I was one but was finally able to get one) (but they are anywhere from $20-$60)unless you buy used.

I thought this might help anyone who is new to these trucks or anyone who needs to look up axle or transmission codes or identify things such as what the c6 pan looks like and how to tell the difference in a 302 and 351w. Move this somewhere else if need be feel free to ad info or change anything.

The easiest way(for me) to tell the difference in a 302 and a 351 Windsor if there is no firing order stamped in the Intake Manifold is to see if a socket will fit on the bottom bolt of the Thermostat housing, on a 302 you will not be able to get a socket on it as the Timing Cover comes up and blocks it. If the firing order is stamped in the Intake Manifold the 302 will read 1-5-4-2-6-3-7-8 and the 351w will read 1-3-7-2-6-5-4-8. Now the 302 shares the same firing order with the following motors: 255, 360, 390, and 460 in Cubic inches in Liters they are Respectfully the 4.2L, 5.9L, 6.5L and the 7.5L. The 351w shares the same firing order with the following motors: 351m and 400 in Cubic inches in Liters they are Respectfully the 5.8L, and 6.6L. And for the Diesel Guys your firing order for the 6.9L is 1-2-7-3-4-5-6-8. Now to differentiate between the 302 and 351w which are smaller than the engines listed above is that the Thermostat housing on a 302 and 351w is on the Intake Manifold and the bigger V8's it is in the front of the block. Another way is to count the valve cover bolts, a 302 and 351w will have 6 valve cover bolts and the bigger v8's will have 8. The 351m and 400 fuel pump bolts are vertical | where as the 302 and 351w fuel pump bolts are horizontal -.

Pic of a 351m and 400(there was NEVER a 400m, IDK how this was started but there is just a 351m):



This is the mounting holes on the block(my 400):



In 1980 Ford Motor Company redesigned the Fullsize Bronco which included the Dana 44 front 4 wheel drive axle being made into an Independent Suspension axle which Ford dubbed "TTB" which stands for Twin Traction Beam, a hybrid of the Twin I Beam front suspension in a 2 wheel drive and the Straight Axle Dana 44 4 wheel drive front axle.(Dana is also sometimes called Spicer as it is the Dana-Spicer Company). All the engines put into the Bronco in 1980-1996 were the 300ci 6 cylinder, the 302ci v8, the 351m and w ci v8's and the 400ci v8 In liters they are Respectfully the 4.9L, 5.0L, 5.8L, and 6.6L.

My books cover 76-96.

Transmission Codes:
Code/ Description
B/ Warner t-85 3spd
C/ Ford Manual 3spd
D/ Warner t-89 3spd
E/ Warner t-87 3spd
F/ Warner t-18 4spd
A(79-86)/New Process 435 4spd
P/ Warner t-19 4spd
B(79-86)/Clark 4spd O.D.
G/ Auto C4
W/ Auto C5
P/ Auto C6 Thru 1977
K/ Auto C6 1978-86
J/ Auto FMX
T/ Auto O.D.-AOD

I will add the rear axle codes for 76-86 here in a bit.

I have to add this the 302 HO has the 351 13726548 fireing order
and this is the prefered firing order if you do a 302 re-build a cam change in all thats needed

heres my 302/331 that was in the Silver '77 in your paint thread



it now sleeps with a few new parts in the back corner of my garage, darn theres that word again LOL

Nice! I had a set of those Chromed Moroso valve covers on my bronco when I got it(see attached pic) and all they did was keep cutting the gaskets, they had a edge on them where as the stock ones I put on are flat so it's all good now. In the pic it had a polished Offenhauser highrise intake, Holley Dual Fuel 750, so it had to go as we were getting 5-6 mpg's, now we get about 15-16 mpg's believe it or not. I've since put on just a regular 351w 2bbl intake and carb.

never experienced any problems (must have been the gaskets you used)
I swaped them out for
'FORD RACING' aluminum covers and went with a chrome 'high rise AIR GAP intake'
hate the Edelbrock carb;

First set of gaskets were Black but had the eyelets around them like yours, and the second set was Fel-Pro cork gaskets.

I thought I'd add to this.

I've noticed a couple questions throughout the forum and other forums of which tranny bellhousing will bolt to which engine.

These engine's use the same bellhousing pattern: 351m/400/429/460, 300/302/351w, I haven't had an FT or FE but here is two that share the same bellhousing pattern: 360/390.

Most manual transmissions have a removable bellhousing which can be swapped out, say you have a manual mated to a 400 and you wanna bolt it up to a 351w, you have to get a 300/302/351w bellhousing, the flywheel and clutch from a windsor, and a starter.

The Mazda M5OD and the ZFS5 spd's have an integral bellhousing meaning that they can't be removed and swapped for a differend bellhousing but a bellhousing adapter can be bought to change the bolt pattern to another.

More in a bit..
