Hello FORD fans!!

I got a heck of a deal on a 390 and am wanting to swap out my 352 in my 64 ford f100 4x4 with the 390. I have done some research and see that the 390 is virtually the same block as the 352, and most of the difference is internally. Now my question is on my current 352 it mounts to the frame on the front with a bracket that seams to be fasened to the timing cover. The 390 I got has the typical bolt holes on the side of the block.

If the 352 block and the 390 block are identical, then would all I have to do is place my 352 timing cover on the 390 block?

Or do I need to buy the engine swap adapters that will allow me to do this with the current side mounts on the 390???

Please help, as I can't seem to find any info on this.

 

Are you sure its a 352...those were 1st offered out of the box in 65 in the trucks..64 had the 292 Y block...if its original, it would have a connecter pipe at the front of the engine running between the manifolds...or those may be capped which Ive seen too.
As far as swapping one FE for another...Im pretty sure the engine mounts are the same...If my memory serves me...a 390 is I THINK a punched and stroked 352...thus a different crank...I know the 360 is a combo of the 2 which may be what Im thinking of...
if Im wrong, and I more then likely am to some degree, by all means correct me. I do know that the heads are the same on both though assuming non smog as in later years.

I was actually wrong. I hve a 65 not 64 and reviewing my vin F11DXXXXX I found that F11 means 4X4 and d means 352. All I can think is that the 390 timing cover has to be diffrent. I'll have to take them both off and compare I guess.

 

First off, welcome aboard!

Secondly, you are correct. The 352 and 390 are of the same FE engine family. That said, you will need to pull the timing cover off the 352 and use it on the 390, that was the 4x mounting set up for just 65-66 if I recall correctly. The rear mount should be on tabs off of the bellhousing, correct? One other thing, your oil pan on the 352 should be a rear sump pan, as opposed to the front sump probably on the 390. You will also want to use the rear sump pump pick-up and pan on the 390. The rear sump pan was designed for the 4x to keep oil in the motor heading up-hill...

Welcome to FTE

With 4WD in a 1965 F100/250 & 1966 F250, the 352 uses a different timing cover than a 352 with 2WD: C4TZ-6019-A (4WD) / C2AZ-6019-D (2WD).

1966 F100's with 352's & 4WD use the same t/cover the 390 does.

Except 1965 F100/250's & 1966 F250's with 352 engines & 4WD, the same timing cover fits all the 352/360/390/410/428 engines: car & truck.

Just bolt your present timing cover to the 390 engine. The same timing cover seal and gasket is used for ALL FE engines 1958/76.

 

Thanks alot guys for the help. I got one other question The 390 also has a harmonic balancer and doesn't look like the 352 does. Will the harmonic balancer stick out past the old 352 timing cover? Or does the 390 have the same crank and I can us the old crank pullies from the 352?

 

There's more than one harmonic balancer.

I963/67 Ford Galaxies w/352/390's & 1965/67 F100/350 352's use one type: C3AZ-6312-E

1968/71 390's in Galaxies & 1968/72 F100/350 360/390's use another: D2TZ-6316-A

1973/76 F100/350's w/ 360/390's use one more: D5TZ-6316-D

Cars didn't use 390's after 1971.

Just use the one you have now. There's no balance problem because the flywheels are the same 1965/71 Galaxie 352/390 and 1965/76 F100/350 352/360/390.

See the truck in my sig? No problems after I did the conversion 23 years ago.

 

Other than the front timing cover what other parts did you have to swap with the 352 and 390?

My 390 that I bought has the oil filter sticking straight out and not down like on the 352? Will it clear the frame? Also what about the oil pans? 390 has front sump and 352 has rear.

 

I assume you searched for this issue but this is a 12 year old thread- The oil filter adapters that angle down (oil filter is vertical) are for car chassis; straight out (horizontal) is for trucks. Same for the oil pan sumps- it'll depend on whether it's 2 wheel drive or 4 wheel drive.

 

Is it wrong to comment on a 12 year old thread in your opinion? 🤦🏼‍♂️

The beauty of forums is for people to help other people and to revisit past threads and to keep conversation going if need be, even if several years later as these issues will pop back up. Seems legit to me.

My 1965 F100 4x4 352 has a vertical filter. I will need to switch it and have the 390 filter vertical as well. I now understand the oil pan differences as well due to commenting on old posts and learning what I need to know in order to restore my grandfathers pickup.

I love these threads, new and old. Thanks!

 

Nothing wrong with it at all- just pointing it out since it's been covered several times and there may be more updated posts with better information.
