I bought a '80 F150 with a lincoln 351w in it. My question is will all 351w parts interchange or is there a cut off on the model years. I really have no idea. what parts are interchangeable from 351c,m,w. I guess i basically need a heads up!

Ex chevy gearhead transformed

 

ohh yeah i'm not 100% sure but i think this engine came out of a 1980 glaxie if thats even possible.
here's the casting numbers
D9AE-6015-ED22

 

D9AE is a 79 production casting number so its possible.

About the only thing of interest between the windsor engine family, that would matter would be the heads and cam. And they do interchange, the heads if going from a 351w to 302 need stepped studs or a washer kit..if going from a 302 to 351w the head bolts need to be drilled to 1/2". As a note, after the 351w D0OE heads (69-74), the 351w and 302 heads other than the bolt holes were identical, and the better heads in most cases were found on the 302. GT-40/ gt-40p/ e7te were all found on 302's, exception being ford put the gt-40 heads on the fist generation lightning 5.8's and put the e7 heads on the efi 5.8's. The cams interchange, only requirement is the firing orders have to be specific to the engine as 5.8 and 5.0 use different firing orders, unless its a HO 302 cam, then the firing order is the same as a 5.8, some of the mid 90's efi non HO 302 trucks, used the 5.8 firing order as well.

The only other thing is you could use cleveland/modified 351 heads on your 351w but it requires a lot of work that just doesn't make sense given what you can find in classifieds today.

Otherwise keep it in the familly,

All 351w parts interchange except for the cranks, some are one piece some two. The 69/70 351w blocks had a different deck height than the 71+ models, so the intake won't interchange with yours, then again why would you want it anyway...haha...The heads off the 69/70 will work on your block and with a little work will perform nicely. All balancers and flexplates/flywheels do not interchange between the 302 (50 ounce) /351w (28 all years balance), around 80 and earlier they will (28 ounce balance), later 302 will not (50 ounce balance).

I know you wanted to know what interchanged between the 351w years but alot of performance parts are sold to 302 owners so the 302 mustang crowd is a great place to go looking for performance parts for your 351w if you know what needs to be done to make it work.

well that was definetely alot of info. Thxs jwtaylor.
so basically the only not interchangeable from 351w to 351 is the intakes69/70 and cranks. Sounds good to me. I have been lookin at headers intakes and cams. Some of them were bought for older model 351w's and i was woriied they wouldnt fit. I am a litle more interested in buying parts specific for the 351w. I have found alot of 351w heads but they say they are ONLY for specific years?

 

As far as 351w heads for specific years that would only be due to one condition, emissions. Some heads have the emissions built in. 74-97 302/351 Some do not 69-74 and 97 1/2 - 2001 gt-40p. If emissions isn't a concern for you then, they should work unless they are aftermarket and have tiny combustion chambers, if youpick up a set of emissions heads and they have the thermacotor ports go to a ford dealer and get the thermacotor plugs, a couple dollars install in the back of the head and call it good.

If you come across a set of heads that state they are for specific 351w years call the company and ask why is that, then lemme know what they say....if you don't mind. later

 

naw i can do that. One more thing the intake and camshaft is there a big difference over the years 69/70 excluded.

 

Go aftermarket with the intake and cam. You won't go wrong using either edelbrock or weiand stealth for the intake and a comp cam or crane would do wonders over stock. Only exception, if you can get a factory stock aluminum 4v intake at a cheap price then go for it, otherwise who wants a big heavy chunk of cast iron on their longblock. Other than in 97 the f250's, actually the only vehicle running a 5.8 that year came with roller cams from the factory, only year roller cams were actually installed in 5.8's. It would require some added money to stick a roller cam in your non roller block and you would be able to get an aftermarket flat tappet for far less out of pocket and make more hp and tq than the stock roller grind. Its worth the extra money to just go aftermarket and go with a cam that is designed to build max power in your rpm range/ application. Just my opinion, later

 

good deal bro thxs. I am plannin on an aftermarket cam.

Havent figured out what intake yet.

 

.....Good luck

 

ok one more quick question then i'll be quiet. aftermarket intake from a 302 will it fit a 351?

 

Nope, the 302 and 351w intakes do not interchange. later

 

Hey JWtaylor, long time no speak. I think the intakes will interchange between the earlier engines and later ones. I know they are differences in the number of intake bolts though. I don't think it's the deck height that makes a difference but the number of intake bolts. I have used an earleir intake on the later heads, before I changed heads that is. You just leave out the 2 extra bolts on the back.
Just like the Performer I used to have on mine before I put on the Stealth. It had 2 extra undrilled bolt hole bosses so you could drill them out for the earlier heads.
hope all is well with you Taylor

I believe your right..I may have my information on the 69 351w intake vs other 351w wrong...as a matter of fact I believe the extra bolt holes is the only difference. 71swissaqua, still happy with your demon carb/weiand intake install? Anything new with your truck? later

 

there are several difference in the intakes. 2 extra bolts in the back is one. The earlier intakes had L shaped water pasages and the newer ones had square. All i can think of excpet the EGR pasages on the newer.
Nothing really new on mine, excpet I did get the water-injection fitted up. just have'nt had time to tune it. i can move my timing up anough to sparkknock at WOD, hit the switch and sparkknock goes away. I know it'll help, I just have to find a good, cheap, esay way to have it come on with the movement of the throttle.
Still very happy with the Stealth and Demon setup. Need to do some more tuning as my idle is still too rich. Trying to find some info on the idle feed resistors. I've heard somewhere that you can place a small piece of wire into the idle restrictor on top of carb and lean out the idle. Need to learn more about that.
how's your truck doing? Having trouble keping tires on the back? lol

Do you need the water injection to come on at WOT or midway?
