352 engine replacement

A 66 f100 I have located nearby has a "bad" 352 coupled with a C6. The truck has a lot of appeal to me and is pretty reasonable.
In addition to the 352 what are my direct replacement engine options? I am guessing 360 and 390. Too bad the 300/240 out of my 71 f100 would not swap out.

Yes, 360 and 390, as well as 410, 427 and 428 and a few others like the 332 and 406. But, be aware that Ford changed the engine mount bolt pattern so some of these choices are old enough to mention.

The change to watch out for is the engine mount bolt holes on pre-1965 “FE” blocks. Blocks before 1965 had two-bolt engine mounts while those from 1965 and later had three-bolt engine mounts. This isn’t a problem if you plan on using a 1965 and later block in a pre-1965 vehicle.

But when using a pre-1965 block in a post-1965 vehicle either adapters or some machining and drilling are required.

I would probably be looking for a 390 and they did not come out until after 65, I think. So that would be OK. Honestly, I would not mind a 352 either. Of course need to buy the non-running truck first.

1961–1963 Ford
1961–1963 Ford Thunderbird
1963 Mercury
9.6:1 — 330 horsepower (250 kW) at 5000 rpm and 427 lb·ft (579 N·m) at 3200 rpm

1963 Mercury Police Interceptor
10.1:1 — 330 horsepower (250 kW) at 5000 rpm and 427 lb·ft (579 N·m) at 3200 rpm

Your '71 six cylinder will bolt in. If the '66 truly has a C6 it is not original anyway, so no matter... Another FE motor is easier, though.

390 introduced in 1961 Ford/Merc Passenger Cars & Thunderbirds, introduced in 1968 F100/350.

360/390 share the same block, the bore is the same (4.05"), the stroke is different: 360 = 3.50" .. 390 = 3.78."

352 B&S: 4.00" x 3.50." Bore the 352 to 390 standard, install 390 rods, pistons and rings. Now you have a 390.

No C6's in F100/350's until 1968. 1965/67 F100/350 352: MX Cruise-O-Matic (14 trans pan bolt holes). 1968/76 F100/350 360/390: C6 (17 trans pan bolt holes).

In a follow-up the owner referred to the truck as a factory automatic with a cruis-o-matic.

Take your time and research the FE engine. With today's aftermarket parts, there has never been a better time to build an FE any way you want. You can just get it running or you can easily make that 352 out perform a factory 390.

Did not consider the prospects that this engine might be "workable." He simply states it is no good.
Need to be talking myself out of this, instead of the other way.
I have to figure out how to get it on a trailer (gotta find or rent a trailer as well). Then how to gracefully get it off the trailer. Uhaul trailers don't have winches.
Do have a fellow Ford truck enthusiast that will allow me to let my truck sleep under the stars at his property as I don't currently have space for it.
This is my favorite year for Ford pickups.

Hard to say if it's rebuildable or not without knowing any history or without taking it apart. Plus many, many people will declare something no good and have no idea what issues it has. As long as the frame, body, cab mounts, etc are good I consider it a bonus to have a non-running engine. To me that's a blank slate and you don't have to pay for what somebody else thinks is a good engine.

That 240/300 is a direct bolt in from your '71 to the '66. If it's in and complete there are no extra parts needed to drop it in the '66.

352 parts are very very cheap to buy at least in this part of country.

One can buy a complete rebuilt 352 for under 1500.00.

I have a friend who has a couple hundred 352/360 cranks turned and ready to go with bearings. You can always bore your 352 to .050 and add a easy to find 390 crank/rods and turn your 352 into a 390.

What is your budget to put a engine in the '66?

I have 3 extra 352's that were excellent running driving engines not taken apart, cleaned and sitting under the workbench. All 3 had never been taken apart before.

1966 F100 352 should have C6AE-R heads on it which are a excellent starting point for a 352 or 390 or even a 428.

It all boils down to the amount of $$ you are willing to part with.

You have 3 EXTRA 352 engines??? Have you considered selling any? I just took the oil pan off my 352 and found what I think are bearing pieces in there. I can't swing a full rebuild this summer and I have been having trouble finding an engine that old around MN.

1965/67 F100/350 352 would have come with MX Cruise-O-Matic (14 trans pan bolt holes), the C6 (17 trans pan bolt holes) was not available in F100/350 until 1968.

Maybe you need to think about this in a different way. Replacing the motor trans is not the big of issue IMHO. Maybe you should think more about the overall condition of the rest of the truck. Body, rust,wiring, suspension, brakes. All that stuff adds up. If that stuff is acceptable, the motor and trans is not that hard to deal with.
Just a thought...
