Hello question about engines for my 69
I just signed up so forgive me if I have put this in the wrong spot.
I have a 69 2 dr fastback that I am looking to restore when I get done fixing up my 67 F-100.
Originally the car had a 351W 2Bbl in it, which sadly is long gone.
What engine should I put back in there when I get to that stage?
Here are some options I am considering:
Put another 351W back in
Put a 390 in it
Put a 400M in it
Poss put a 429/460 in it.
What would be the pros/cons with each?
I look forward to hearing from you guys on this.

I'd put a 408 (stroked 351W) in it. Or at least a replacement 351W. Staying with the Windsor means that your mounts will work as is. Going with an FE means new springs (and maybe brakes) and locating the FE-unique parts like the engine frame mounts. A 400M is a real oddball performance wise, but not a bad choice if you just want to chug around town. I personally wouldn't do the 400M since they have terrible combustion efficiency with stock heads and pistons. I'd avoid the 385 series just based upon the weight issue.
Honestly, none of these are bad choices. It just depends on what you expect and how much you want to spend.

Thanks for the info!
I guess one of the reasons I was thinking of a 400 was that my folks had one in a 74 LTD and that thing kicked some serious butt.
I have heard that there was a difference in the 351W's from 69 to the 70's is that true?
Currently on the project budget I am looking at a good reliable engine with some kick but not investing future family members to finance it.
Also how hard would it be to find th FE mounts anymore?
Sorry for all the questions.

I don't know of any difference between '69 and '70 351Ws. You're not referring to the 351W and 351C, are you?
400s are not bad but, again, they have terrible combustion efficiency due to the lack of effective quench in the combustion chamber. But good heads and pistons can fix that.
The part you need to place an FE in the car are the adapter plates that mount between the frame and the rubber isolator. Not impossible to find but there are other issues, such as the heads and exhaust, that are particular to FEs in this chassis.
Again, another 351W would be the easiest route.

Only advice I'd give is stay away from the 351M/400's. My father has built engines for over 40 years, and is not fond at all of those engines. _________________ NMCB 28 Seabee Battalion

Nope just the 351W's.
Thought I read somewhere there were some differences in them from the 69-about 74 and then 75 up versions.

Other than changes in the combustion chamber size, they're not all that different from '69 until the last one went out the door in the 90s.

Gerry, do you know what cubic inch this 5.7L is that's in the 2007 Shelby Mustangs? They say it produces 500 hp. I'm wondering if it's an evolution of the Windsor. _________________ NMCB 28 Seabee Battalion

It's a mod motor (modular engine). 5.4L. Nothing in common what so ever with the Windsor.

I totally agree with Gerry. The 351w is a great platform which can be stroked now or later if desired. The difference in '75 and later 351w's is that they used 302 size valve and port sizes. Aftermarket parts are cheap and plentiful.
A 400 is not a bad engine, but it is big and heavy and shares a bell housing pattern common with the 429/460.

Thanks all for your help.
Looks like I will go with a 351W then.
Supposedly though a co-worker offered a 390 out of a scout if I wanted it.
Suppose it wouldn't fit in there would it?

sure a 390 would fit, some 69's came with 390's. you'd just have to use 390 mounts. don't know if a windsor tranny will bolt up to a 390, though. _________________ NMCB 28 Seabee Battalion

Unless your hard up for something else you made the right decision. 351W!
Not that I'm a huge fan but just from a tech. standpoint, it will save you a lot of conversions and headaches replacing all sorts of other mounts and things to attach to a new motor type. _________________ ___________________

Just wanted to say thanks to everyone who replied.
I will be going with the 351W and having some fun with it.
Will try to put it in front of an AOD so I can get mileage and possibly put a nice low set of gears in it.
Otherwise I will have the FMX looked over and put that back in.
