Hi all, I have a 67 F100 4x4 that I am looking to do some motor work on. I was told that the truck has a 360 from a 79 in it, but I would like to know for sure. My plan is to stroke it to 390, & freshen it up. later I plan to convert it to FI.
Can anyone point me to a resource for id information? Casting numbers?
My other question is, would I be better to swap this motor out for a 351M? I have a complete drivetrain with the M motor, but am not sure which engine would be best. I plan to use the truck mostly off road, not as a regular driver.

Many thanks
Stacey

 

Casting numbers cannot be cross referenced to part numbers.

352/360's have the same stroke: 3.50" / 390 is 3.78."

1968/76 360: Despite several bare block castings numbers, the short block is the same for all: C8TZ-6009-G / Same thing holds true for 390's, all the short blocks are the same: C8TZ-6009-H.

All the 352/360/390 1965/76 F100/350's (and 1965/71 352/390 cars) bare blocks were cast as 352's. Only when finished, can they be something else.

JMO, the only place I'd put a 351M is in the scrap pile.

It's a smogged up terd of an engine, and is very prone to cracking cylinder heads.

 

Stacey, To add to what Bill has said and he let slip by, if your V8 is big and is a 79 it is likely a 351M anyways. The last FE was built for 76.

The 360 is a destroked 390 so adding a 390 crank and rotating system is easy.

Me no see-um FT in Post #1, musta slipped by...looks like FI to me.

 

I have been searching these threads for info to determine what engine I have in my 69 F100 SB.
According to the VIN its a 360 but of course I was told it was a 390 when I bought it. I pulled the motor and it has casting that say 352. What is a 352? I have read it has the same stroke as a 360 and it often looks like a 352 is refered to as a 360. So are they 2 different engines?

And if the quote above that they are all cast as 352's how can I tell what I have?

VIN F10ACB46943

Thanks!

 

352 = FE engine introduced in 1958.

Used in cars thru 1967, used in F100/350's 1965/67.

All 1965/72 352/360/390 bare blocks have 352 cast onto them, because all these engines were cast as 352's.

Only when the engine is finished could it be something else.

The FE 360 and 390 engines were introduced in F100/350's in 1968, used thru 1976.

The 360 was a truck engine only, never installed in cars.

The 390 was introduced in 1961, used in cars thru 1971.

What the heck?

What VIN decoder did you use that says your truck has an FE engine?

What VIN decoder did you use to come up with the fact your truck is a 1969?

Neither is correct.

This is the VIN you posted: F10 A C B46943

F10 = F100 2WD

A = 240 1V I-6

C = Ontario Canada Assembly Plant

B46943 = 1967 (1967 Serial Number Range: A00,001 thru B82,000)

Where did you get this VIN?

Off the registration (title), or off the Warranty Plate (W/P), located on the left door face below the latch?

If off the W/P, peeps swapped left doors due to damage, forgot to swap over the correct W/P.

Compare the VIN on the registration to the VIN on the W/P, see if it matches.

If the VIN turns out to be correct, your F100 is a 1967.

And...the engine has been swapped, and it could be any FE engine size: 332/352/360/361/390/406/410/427/428, from gawd knows what vehicle.

FE engine - 5 valve cover bolts.

On sale day, 352 & 360 engines magically become 390's.

 

My Bad!
I grab the folder with all my paperwork and had written that VIN down on the outside for a truck I purchased as a parts donor for this project.

For the information I used the front section of a parts supplier catalog, I beleive it was NPD.

THe correct VIN right of the title is:F10YDF30381

It should be a 1969 F100 3 speed with a 360...at least I think so

IT has been sitting for the past ten years and I finally got around to pulling the motor out.

I have a 302 complete drivetrain out of a 91 mustang I was going to use but I am trying to keep this a low buck parts chaser or even more on the lines of a rat rod if you know what I mean. low buck all the way

Thanks for the fast reply & info

 

My bad!

I just noticed the above was your first post, so...

Welcome to FTE

F10 = F100 2WD

Y = 360 2V

D = Dallas TX Assembly Plant

F30381 = 1969.



360/390's have the same bore: 4.05"

Stroke: 360 = 3.50" / 3.90 = 3.78"

 

You said the number plate on the door is the warranty plate? not the VIN? I have been all over the three F100 I currently have and always thought that was the only VIN. I did see a metal plate with a single metal staple holdin to the drives side cowl below the hood just behind the master cylinder. I just figured it must have fallen off the other two trucks and since it was held on with a metal staple I figeure it was a info plate and not terribly important.

 

Sorry for so many question but you seem like the man with all the answers. It has 5 VC bolts but is there any other way to identify it as a 360 or the original engine for the VIN? It certainly would seem more like than not after forty years that is had been swapped out. But you never know it could be original to the truck. THanks again!!

 

The Warranty Plate on the left door face has more info than just the VIN on it.

The following refers only to 1966/69.

First Line: VIN

Second Line Codes for: Wheelbase / Color / Model / Body / Axle / Trans

Third Line Codes for: Maximum G.V.W. LBS / Certified Net H.P. / R.P.M. / D.S.O.

I can decode all this info.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Metal plate on firewall = FoMoCo "buck tag" installed at final assembly.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
"Numbers matching" on engine/trans parts is a GM thing.

1968/76 360/390: There's no way to tell one of these two FE engine apart without measuring the stroke.

All FE engines from 1958 thru 1976 look pretty much the same.

All 1965/76 FE engines look identical.

 

Now I can understand why they all become 390's on sale day! Thanks again for the info. The guy I bought it from said he just went throught the engine, rings , bearings Oil pump, timing chain etc. I have an engine test stand so I am going to try and fire it. If it runs out good I'll drop it in with the original 3 speed. If I have to rebuild it I'll just drop the late model EFI 302/auto in it. so much for low buckn it!

 

What's the difference between a 360 and a 390?

The 390's crankshaft, connecting rods and pistons are different than 360's use.

Everything else, including the block, cylinder heads, valve train, rings, rod/main/cam bearings, camshaft, oil pump, timing cover, timing chain & gears, waterpump, intake/exhaust manifolds, gaskets & seals, yadda...yadda....yadda is the same!

The A/T flexplate is the same for all 1965/76 352/360/390 engines, with either a C6 or the 1965/67 C-O-M. This includes the 1965/71 cars with 352/390's.

1965/76: The 352/360's use an 11" clutch, the 390's a 11 1/2" clutch. So the 352/360 flywheel is different than the 390's. This also includes the 1965/71 cars with either 352 or 390's.

 

I know what you opinion of the 351M is but what I don't know is if a the bell housing bolt patterns are the same? if I pulled out a 351M would the 390 bolt up to the c6?

 

351m bell pattern is different than FE bell pattern.

351m & 400 (with one exception) match the 429/460.

FE has its own pattern.
