Had Bill decode my number tag and decided my '61 F-100 came with a 223/3speed.
I knew from the start that the 3 speed had been ditched in favor of a granny low 4 speed(left the column). Now, as I'm pulling all that out to go with the 302 I find some wierd stuff.

First, this shortbed truck had a 2 piece driveshaft. As I unbolted the support bearing I find that the bracket had been torched out of some other truck and bolted in place on this one.
Second, the intake/exhaust on my motor exited out the drivers side of the engine and ran down the drivers side to the rear. While I was cutting it out I noticed a factory, rivited to the frame, muffler bracket on the passenger side along with a couple of old aftermarket hangers.

Also, in pulling the trans I peeled back the carpet that the PO glued to the floor only to find a lovely patch panel about 14" by 18" rivited to the hump area of the floor. This had the cutout for the shift tower, but when I removed it, I found that it was covering a hole big enough to drop a 12 pack through(set off to the side...car 4 speed maybe?).

My main question is about the exhaust though. Which 6 cylinders had the exhaust on the passenger side and which ones had it on the driver's side? Just curious in case I decide to do something with this old motor...might be nice to actually know what I have.

Beer's on me if you got this far.

 

The exhaust started in the drivers side manifold and curved under the back of the oil pan to the passenger side and hung by that bracket.

Most stuff done by PO's is baffling.

The hole in the floor was more than likely for an aftermarket shifter for the original 3 spd, It used to be pretty common when the column shifter gave up the ghost to use an aftermarket shifter rather than fix it. I can remember when all parts houses had the 3 speed shifters in stock.

 

All 1961/64 F100/750's / 1965 F100/250 4WD's / 1966 F250 4WD's / 1965/66 F350's / 1961/69 N/NT500/1000's have a removable blank panel (block off plate) in the floor at the hump.

C1TB8112110A .. Blank High Tower Plate / Fits all of the above.

When this panel was removed, a 4 or 5 speed transmission could then be installed.

What the OP's truck has...is the (homemade?) plate used to install one of these transmissions. It was originally bolted on, not riveted.

Think about it, as it's a matter of economics. The same floor pan was used for all these trucks, so Ford punched out the hole in the floor pan, then used a blank panel if a A/T or 3 speed trans was installed.

If there was no hole punched out, Ford would have had to make a separate floor pan for a 4 or 5 speed transmission.

 

Bill the hole off to the side he's talking about was not original was it. I wasn't talking about the oricinal hump cover, but the six pack hole.

 

Why would someone cut a hole in the floor pan to install a 4 speed, since there is already one there?

Of course, some people are clueless beetle-brained idiots and so...wouldn't know that panel is removable, even though there are 11 bolts plainly visible that are used to retain it.

As Dave (garbz2) just typed in another thread, what some PO's (and present owners, alike) fabricate on these trucks, is mindboggling.

 

Number dummy what the hole in the side was more than likely for an after market 3spd shifter used before the 4spd was installed (my guess) as the ones I remember you had to mmake a fairly large hole in the side of the hump. Lots of peaple used them instead of repairing the shift tube.

 

Hate to break the news, but ford did two floor stampings. In fact you must cut out the floor to install the high hump in a 61 to 64 if the truck did not leave the factory with one. for 65 and 66 the same thing applies if the truck came stock as a three speed column shift it has no hole. If it had a floor shifted otr 4x4 it had the cutout and an additional panel to clear the tower on the transmission. Also if in 66 ONLY if the truck came with an automatic there is an additional small oval panel for the intermediate band adjustment on the Cruise O Matic........

Here are two different parts catalog references with the same info, plus. If you don't believe me, I suggest you get the parts catalog and look this crap up for yourself.

Frankly, I'm sick and tired of wasting my time helping people, then to have someone chime in and argue. The usual whine is: "My truck doesn't have that."

 

Not wanting to argue but I swapped a 4spd into my 64 F100 and though the floor had a dimple outline of the cutout I had to cut it out and use the bolt in one out of the 4spd donor. Not sure what was up but my dads 3spd 64 did not have the bolt in plate but did have the built in pattern.

 

Oops, didn't mean to start a forest fire.
This truck has no factory removable floor panel. I peeled the carpet all the way across and all the way back to the seat, also been underneath with a good light. I had a '53 F-100 and a few old Chev trucks, so I'd recognize it if I saw one. The big hole looks to have been chopped with an air chisel...or an axe :-(
I didn't think about a floor shifter for the 3 speed, but that could be a possibility.
The patch panel that was there looks like somebody took one of those galvanized drip pans you use to keep drips off the garage floor and cut it up. I've talked to my boss and as soon as I get it running where I can get it to the shop we'll cut it out square and fix it right.

This is one of those things where the parts books mean jack......I don't care what the PN say. I speak the gospel....I know i have parted well over 200 of them.

The Floor shift floor was stamped and trimmed with cage nuts installed in to retangular openings to accept the through machine screws.

This is a 1963 floor in a Model 66 uni



This is the underside of a 1964 Model 81 conventional



You will notice that neither is cut out by the factory, or with any cage nuts.......Just an old hole i had Jr fix where an indy shifter was used on the ford Ld3
