    Posted: 15-March-2019 at 10:29AM
Hi,

I'm pulling the 351M/400 from my 1976 Gran Torino and installing a new 351W crate engine.

Does anyone know if any of the front accessory brackets will transfer over from the Midland to the Windsor? I know Midland and Cleveland blocks are similar enough. I'm realizing that these brackets are hard to find new or used and people have suggested trying to see what fits and what doesn't.

So if anyone has any experience on this, I would greatly appreciate it. I am going for stock V-belt setup and not spending $1K plus for a serpentine conversion from March Performance or other.

Also, I am told that since the Windsor block was available for the 74-76 Gran Torino, that I would just need different engine mounts and no modifications to the frame are necessary. Can anyone confirm? I already know I will need to get another C6 transmission, as the bell housing was different between the Midland/Cleveland and the Windsor.

Thanks in advance!

No brackets will swap.
Best bet is to find a car with 351W and get EVERYTHING off the same engine.
I say EVERYTHING because these are several different bracket schemes for the 351W, and mix-and-match is a crapshoot.
your alternator should work, as well as the P/S pump (after changing the brackets)
Engine mounts are different. Torino doesn't use a frame bracket, the mount saddles the frame itself. The mounts have a "Left" and a "Right" part #
If you get the mounts on the wrong side of the block, it won't line up.

If you wanted to go with a budget serpentine setup the 351w was used in F series pickups and E series vans until 1996. And Google says SUV''s until 2001.

You'd be better off going AOD for a trans, a small-block C6 is rare, parts are expensive, it has a very high HP loss through the trans(something like 70 HP IIRC), which is ok with the torque of the M series, but the Windsors aren't quite at their level.  the AOD can be built to handle the horsepower and torque, you'll get better mileage, and parts are a lot more available.  Something to think about.

Ideally, finding a mid to late '80s Crown Victoria with the 351w/AOD would solve your engine dress and trans issues in one shot.  Most were fuel injected, but didn't have the roller cam setup. This means you can use a regular distributor(as opposed to the hardened gear you'd need with the roller cam), and bolting on a 4v intake is easy.  Later ones did also have the serpentine belt setup

Hope I haven't muddied the water too bad! LOL Good Luck!Thumbs Up

Hi All,

Thanks for your replies. I am not wanting to go with any form of serpentine setup. I am keeping the engine and transmission stock, thus I am going for stock V-belt look. I have contacted Desert Valley Auto Parts in Phoenix (specialize in older car salvage), they are working on pulling an entire setup from one car (brackets, pulley's, hardware, etc) and shipping it to me.

I seriously thought about getting new AOD transmission, but I am getting a really good deal on a rebuilt C6 transmission with less than 3K miles and I cannot pass it up. Since this car is going to be a weekend cruiser, I am not overly worried about fuel efficiency (although I am to a small extent).

Thanks again for everyone's input!


Regards,
Mike

I would ask them to provide some pics of the brackets as they are before disassemble. Makes it a little easier to put together correctly the first or second time.

You might be able to get the motor mounts new from a parts store, but there seems to be some issues with 351 motor mounts for Torinos.  I know some buys were trying some new ones for 351C's and they didn't all work or fit correctly.  So, just be warned you may have to try several different brands to find one that fits correctly.

302, 351w, and 351c all use the same mounts.

imo, doing a 351W stroker eng swap today is one of the BEST ideas for big torinos

doing a big 451-461 ci W block stroker is not a problem today... https://www.corral.net/threads/351-maxx-block-9-5-9-750-td.2479966/
