I bought a 1969 Ford F350 and was told it had a 390 in it.
The VIN has a Y not a H and on the front of the motor there is a mold that says 67 352.
Befor I start buying parts for it I need to know what motor is in it.
If anyone can help with this it would be a big help to me.
The valve covers have 5 bolts.
Thanks

 

Welcome to FTE, many 360 suddenly became 390 when sold as used trucks, the 352 on the block is a simple casting number and does NOT lead to it being a 352.

there only one test you can do without tearing the whole engine down and here what you need to find out

first you need a wooden dowel 1/8 x 12 inches

Step 1: remove all plugs
Set engine to 0 TDC and stick the dowel in the #1 cyl. Mark it with a marker at the plugs open edge

Step 2: rotate engine 180* and mark the dowel once more

Step 3 measure the marks, if there 3 1/2 inches, you have a 360 stroke, if its 3 3/4 inches, then you have a 390 or up stroke

This test is NOT 100% accurate, But just a way to get a idea. to be 100% you have to remove a head and measure bore and stroke.

 

honeyjbr, I believe I have read there were no 390s installed in that size truck that year, but no one knows how many engines could have been put into the truck in 40 years.

390 is becoming more of a term like stepside than for the actual engine size.

Finding a 1/8" wooded dowel like Madathlon suggested might be a little tough in your area. I have found a piece of white house wire will work better when I last did it. I have also found that a friend rotating the crank while you rest a Sharpie on the manifold marking the wire as it slides by was easier for me.

Thanks to Madathlon and jowiler for the help.

I am starting to rebuild a 1969 Ford F350 flat bed with a dual rear end.
I want to put a newer engine in it and a C6.
It has a 4 speed with low range first gear in it now and a 390 (not completely sure of the engine size).
Is it possible to put a diesel engine in it or what engine would be best?
I will be using this truck to pull a large boat.
Also will the parts for a 390 fit one of the small big blocks?
Thank you for the help.

 

A 390 will pull large boat just fine.

For my use, if I was gonna go diesel, I think I would buy a wrecked diesel truck and move my sheet metal to that chassis, if you are real fond of the bump side.

carcrafter22 did a full diesel conversion on his truck, here the link to part of it, contct him for more details

Thank you Madathlom and John for the link and information.

 

Is there a difference in the Frame of a 1969 F150, F250, and F350?
Thank you.
Ben

 

Ben, The 4 wheel trucks chassis are pretty much the same, with some minor differences.

What are you wanting to do?



John

 

I have a 1969 F350 flat bed that I am going to use for parts.
As I was pressure washing the frame I came across a weld just behind the steering box.
The weld looks good but I am not sure if I should use this frame or find another one so I am looking for information on what frame I can use for this one ton 4X2.
Thank.

It be faster and cheaper to clean, and weld a reinforcing plate over it, cracks by stearing boxes are common. and to fix proper isnt hard to do

 

I agree.

Whoever said there wasn't a 390 engine in '69 Ford F-350 trucks is wrong. Here's the first part of the Serial No. from my '69 F-350 Crew Cab: F35HCE5----. You can see the Factory thought they had a 390 in this truck, too! The 390 was very popular in '69 and certainly someone wanting a 1 Ton Truck would want the additional power which is 40 more horsepower according to the factory over the 360. I wonder where these myths come from? I have heard several similar to this.........
