Have question regarding 351 W
I am in the final process of choosing an engine for my 1951 F1 and am down to a 351W or 351Cleveland. One question will the larger block fit OK ? or will I have clearance problems.? Will an AOD fit both engines?
And what about the difference in weight of both engines? Any comments are greatly appreciated.

I'd go with the 351W for several reasons. The 351C hasn't been produced since 1974 so parts availability and cost is an issue. The 351W was made until around 1990 so they are much more plentiful and parts easy to find. The 351W is like a 302 on steroids but the 351C is an entirely different engine. Size wise they are about the same so either would fit your engine compartment but the 351C is about 25-50 pounds heavier. If you ever wanted to go with EFI, the Windsor engine would be much easier to accomplish...

This is true
Vern said it as it was. Thats why I put a windsor motor on my f-1. I was trying to find a cleaveland but no sucess here in the rockey mountans in canada. so i did do research and vern is right parts avalibility was my main concern. Besides aftermarket parts are more ready for the windsors. As for cleavelands. And as AOD I do not know as i bought a econoline with a c-6 attached but i wish i can have o-drive.Not sure can a AOD bolt up to 351w?

No bother
Well I had no trouble. In fact I had a 302 with c-6 installed in high school years ago. My 50 ford had just stock front end and their was loads of room
Keep in mind this year i installed my mustang ii ifs and changed over to a 351 windsor and it fit fine
remember I have heard of putting in a big block into these trucks Their is plenty of room.

Either engine is a good choice. It really depends on what your plans are for the engine. The Cleveland will be a little more difficult to fit headers, if you wanted to.
Both engines have the same bellhousing bolt pattern so yes you can run the AOD behind either of them.

It really depends on personal choice both are great engines. Which engine does he prefer? Both have plenty of aftermarket support. I lot fewer people are running the Clevelands now so it would be a little more unique. Comparing them side by side stock the Cleveland will out perform the Windsor. If you are going to build them it's a pretty much a wash.
I'm going to run a Windsor in my 54 but that's simply because that's what came in my donor truck.

I think the deal breaker for me is that you can find a "roller" 351W motor which eliminates all the problems everyone is having with flat tappet lifters and little to no zinc (ZDDP) in the oil. You can read more here: What is with this oil ZDDP content and do I need it? - THE H.A.M.B.
I have a 390FE in my 1955 F100. I love the engine, but I if was to do it all over again I would go with a roller (1996-1997) 351W stroked to 393 cubic inches.

Yes you can covert a 390 to roller. It just takes more benjamins.
There is a lot of debate over what FE stands for. After building my engine (Edelbrock heads, intake, carb, comp cam, adustable rockers, forged pistons, etc...), I beleive FE stands for Freakin Expensive! It was going to add another $500 for the roller hydraulic lifters and another $1200 for the roller rockers. I found a 1997 351W (car-part.com) in my area which is completely roller for $850; 60,000 miles. I have a lot more in my cylinder heads than that entire roller motor which will definately last another 100,000 miles. Just my 2 cents.

He was talking about 351C vs. 351W. The FE is going to be more expensive.
You can buy a roller 351W but it still has a stock cam. So if you want more power you still need to replace the cam.
Don't get me wrong I like the Windsor! 2 of me 3 Fords have the 351W. And ones a roller motor.

The other funny part is if you call your local oil suppliers (not the parts store), you can usually find regular old oil with zinc for fairly cheap. We are going to start running Circle Oil cause a local guy distributes it. We got in good with him after he spotted my friends hot rod truck on its test burnout day...he gave us a hell of a deal!
No matter the mill, building it will add money. FE's, yeah, they cost a little more than a Windsor. Basically, if you intend to build it up, I would go with the Windsor simply because aftermarket speed parts can be found at swap meets, and they are cheap off the shelf. If you only want a little cam, maybe an intake, it wouldn't make much difference which mill you choose.
