Found a running 351W still in an 80s Grand Marquis with only 60k today. Guy said 200.00 for the entire thing including the A/C, power steering, etc (which I'd simply list on eBay). For another 150.00 bucks I can grab a couple 9" rears with limited slips though I have to start measuring first. Loads of Crown Vics & Lincolns from the 80s. Not sure which rear would fit our 67 just yet though.

So for 200.00 bucks should I drop it in instead of the 289? Was planning to refresh the 289 anyways so why not a 351w!

 

351. If it's an 80's block then it's prolly alreay a roller block so a rolelr cam setup is cheap. And a 351 block will make and take more power.

 

Hmm.. Hadn't thought of that. Didn't think they switched over to rollers until the 90s to be honest.

 

Around the mid 80's. The 302's started getting rollers in 85 I think.

Just did some quick checking, and it seems like the 351's started getting rollers in the early 90's. Still though, it's not that hard to run a roller cam in 1, and the 351 is a better platform to build off of than a 302.

 

It's not exactly a simple drop in.

It's taller and wider than your 302. Exhausts don't match. It might be too tall, and you'll need a hood scoop. The oil pans don't match. You'll have to swap in the computer, and an EFI fuel system. Or swap intakes and distributers on the 351W. There's a few other minor details, too.

 

351 headers, and an intake and dizzy for the 351. With a short air cleaner it might clear the hood, the 351 is a bit bigger. It doesn't need to be EFI though, stick a carb and 351 carb intake on it and it'll be fine. It will need a different oil pan though, since the one on it is prolly a dual sump instead of a front sump. Mostly minor stuff, well worth the hassle to have a 351 I think.

 

Don't remember right off hand but I think the 68 Shelby fiberglass hood is a bit higher then the original. Not sure by how much. My plan was to do a basic rebuild to refresh the 351 and inspect the block and internals. At this time I'd step up the cam slightly, swap out the stock intake for an Edelbrock Performer intake manifold, top it off with the new Edelbrock Performer 600cfm carb from the 289 for now. Replace the fuel, oil & water pumps, add a double roller timing chain, spark plugs, yadda-yadda.

I have yet to buy new headers, exhaust, rad, etc so I still need to buy those without having new 289 parts laying around. The only NEW 289 specific item is a 10.4" RAM Clutch kit I bought from NPD which I can return and get the 11" 351 clutch kit instead.. 45.00 cheaper to if I remember correctly.

I know there is a block size difference though its still a "small block".. The bell housing for the 67/68 4-speed toploader should still bolt onto the 351w correct? Just need to swap out for the 11" clutch kit.

Thanks for the help btw .. My internet access is sporadic here right now so checking/replying whenever I can.

 

I dont know how much taller the shelby hood is, but with a victor jr intake I had to put a 3" cowl induction hood on my 68 coupe and still have to run a drop base air cleaner.

On the headers, the only ones that jegs or summit would tell me over the phone that would work with a standard trans was the hooker super comp headers. The biggest thing is trying to clear the z-bar. Also with the z bar thing, the hooker super comps make you buy a 69 z bar for their headers. I went ahead and drilled and tapped mine for a grease zerk so I could grease it w/o pulling it off.


The bellhousing still bolts up, no problems there. The biggest thing was trying to get the headers on w/o bursting a blood vessel, those super comps were a pain. Use quality gaskets with those also, they send you some with the headers but those are junk.

Also a big thing to watch for is that the windsor block has the hole on the driver side that is tapped for the pivot ball on the z-bar for your clutch. With out that drilled and tapped, you would need a different clutch setup (cable or hydraulic)

 

Forgot to mention that some of your acc brackets won't line up correctly because the deck is taller on a windsor vs a 289/302. I just run an alternator and water pump on my car, but I had to do some work to make my alternator bracket work.

 

jason.. thanks for the info. Shouldn't be an issue with the z-bar as I'm going with a hydraulic clutch. I'm wondering if it'll fit or not now with the 68 Shelby FB hood. The wife wants that hood and we've already purchase it. Any chance of getting a measurement from the motor mounts to the top as a reference? I'd like to install the hood and see if it'll fit or not before I make the 2 hour drive to get it (plus a few more hours to pull it).

Thanks
