I am supposed to pick up a '62 Unibody today.  The very early plan is to replace it's 223 with a 292 out of my '64 F-250.  Are there some problems to be encountered that I dont know about?

You'll have to add a mount to the frame, at the front of the engine. Other than that it should be a bolt in.

Charlie, does the bell housing and trans need to be swapped too?  Both the '62 and '64 have the four speed.  I was looking at the I-6 bell mounts yesterday and they appeared narrower than the V-8.

What year is your truck?  The '62 grill looks like yours.

By charliemccraney - 14 Years Ago
The Y bell housing is different than the I6. I think transmission should mount to the Y bellhousing.



Mine's a '61.

Thanks Charlie.  Paid for the truck today and got the title.  Will go over tomorrow and try to start it.  Luckily it is only 1 rural mile away.

The '62 gives me a lot more enthusiasm than the '64 3/4 ton.

My friend, you and I are trying to do the same thing almost exactly, and we are probably the only two people on the internet right now who are. I am mounting a 292 from a 64 F-100 into a 63 ford Fairlane, which used to have a 170. I found that it was more sensible to use the truck transmission, as well as to notch the inside of the engine compartment at the shocks.

Google "fairlane Y-Block" to read about my struggle with closed minded people who didn't like this idea. I must say, I found people who are into 50s cars much more agreeable about this.

It also seems to make a lot of sense to use the truck's back axle, as the F series has a wheel base in between a Galaxie's and a Fairlane's (if you are using a falcon, you'll likely need a different driveshaft). What car is it, exactly?



Anyways, here's some of the work I did to research this (you must understand I originally thought I had a 312)

This shows how you must notch the fender wells demonstrated in a 63 (or was it 64?) Falcon, even smaller than my Fairlane.

Jester I think your job is a greater task than mine.  The '62 is a Unibody pickup, F-100.  The biggest  task will be getting the body and paint in good order. 

The '64 small block is in great shape and the heads are being redone now.   If my 312 ever becomes reality it can go into the '62 with a nice trans too. 

Hope the 9 inch rear is a limited slip, but will find out for sure shortly.

Wouldnt it be nice if some local rat rodder wants a running I-6 BigGrin .  Did some searching on ebay and found parts for the 6 bangers to be CHEAP.

46,

Since you've paid for the truck, it's probably too late but I hope you got under it and checked the cab mounts and the torque box. They tend to rust out. You will have problems if they are bad. Repairing them is not easy. All of the pieces for the torque box have to be made. Not available new. I am so fortunate that I will get to experience the replacement of both cab mounts and the torque box!
By 46yblock - 14 Years Ago
Well Charlie, you probably know that I didnt... and what the hell is a torque box?   Maybe luck will prevail, but thanks for the heads up.  Will check it out when in the barn.

you gonna start stock-pileing F-100's Mike?Tongue

was that the one i saw on craigslist there in Williams?

By 46yblock - 14 Years Ago
Yes, the same one Dustin.  No I dont stockpile much of anything.  Sometimes even sell off items that I end up having to buy later.  Having said that there are distributors, big 2100's and rocker assemblies that are starting to gather.   

The 3/4 ton was a gamble that paid off engine wise, but didnt want a 3/4, plus its windshield had been BB'd to pieces.  The unibody was available for as much as the windshield would cost on the 3/4. 

Maybe some of the '64 can be used on the earlier model.  Plan to make a poor man's engine testing stand out of the front of the frame.

The cab mounts are easy to spot looking throught the front wheel wells. The torque box reinforces the structure between the cab and the bed. The front bed bolts go through the torque box so that'll give you an idea where it's at.

I didn't know about any of this when I bought mine. If I knew then what I know now, I would have offered about 1/3 what I paid for the truck. Oh well!

Irregardless of information learned the hardway, your ride is NICE.  There is something about the unibody headlights that give them a "Sleepy Eye" look Cool .

I'd buy the I6, I'm gonna need a new engine for my truck, but shipping would kill me (...Alaska)

For a while, I thought I wasn't alone...oh well, that means my car will be even more unique.

Hang in there Flying Jester.  Unique is neat, but sometimes lonely.  As far as I can tell there is only one other '46 pickup with Y-block in existence.

Too bad you arent closer.  The six runs and sounds good.  No smoke.  getting ready to put it on craigslist.

Checked the areas Charlie mentioned and all is well.  Whew!  Will need to switch a lot of the front sheet metal pieces with the '64.  It will cut out a lot of body work.  The project is going to take some time.

By bloodyknucklehill - 14 Years Ago

By 46yblock - 14 Years Ago
No more for me Hehe .  I'm trying to pare down the initial cost of the two Slicks.  Actually have both of the AM radios working, and only need one.  Guess where the other is going?

Does anyone know how to remove the stainless steel molding that goes around the '64 windshield?

By Bigwin56F100 - 14 Years Ago
Mike,

On the windshield stainless. You have to cut the windshield rubber on the inside of the cab to remove the windshield, then once the glass is out you can remove the rubber from the glass and then remove the stainless from the rubber. Installation is reverse order EXCEPT:



If a 61-66 didnt have custom cab stainless from the factory it will not fit> The cab windshield opening has to be enlarged just a little for the trim to go in. Believe me I've tried!



If you plan on using the trim in your other truck you will be able to compare the openings of the 2 trucks. The dash lower corners need to be trimmed if I recall.



Good luck

Thanks a bunch Kevin.  Not knowing what else to do and with the front windshield shot up, this afternoon did exactly what you said.  Cut the rubber from the inside.  It was tricky getting the windshield out intact, as I was afraid it would disintegrate and screw up the molding.  I am happy to say it is removed with not a single extra ding, bend or twist BigGrin

Also very good info on using the molding on the 62 that didnt have any, although I dont plan on putting the molding to that use.

Before you start ditching parts take a good look. You mentioned swapping front end pieces. The 62 upper valance is different than 64. It's an easy fix though, the F O R D is spaced differently. I like the 64 valance better so it's what I used.
The Y block mount is pretty easy to weld on the front crossmember - just line it up with the 223's mounting hole. Pretty easy to remove from your 64 too, just cut through the welds on the top & sides and give it wack with a 5 lb hammer - comes right off, lol. I went through the same thing with my truck, but both ways - it was a 292 truck, I had a 223. I had to cut the mount out to drop the 6 in, then when I got a 292 I had to weld it back in place.
64 valance on a 62 Uni.

By 46yblock - 14 Years Ago
Greg, you have a very nice unibody!  It looks like your headlight rings/trim are '64? 

I am going to use the '64 front valance with the 62 grille.  I like the 62 grille better. 

By Greg D - 14 Years Ago
Thanks

Those headlight rings came off a 62 parts truck with the grill. All Slick headlight rings are the same as far as I have ever seen - only difference is chrome steel - 61, or painted steel & aluminum.

My Uni is in the garage right now, total redo of the body, filled seams, shaved drip rail and new paint - same style. Working on the roof now.
