Hello all. I just got an 88 f-350 4x4 and I assumed that it would have a 460 in it. I ran the FTE vin decoder twice and guess what. It comes back 351. Is this 351w, 351m(which I have in my 79 f-250), or what? I am surprised that a truck this big would be powered by a 351, but it does seem strong. The vin is: 2FTJW36GXJCB07897. Any history on this would be appreciated.

Look ontop of the intake manifold it will tell you 5.0 or 5.8. If you have a 460 you will have a wierd lookin intake. My F350 has a 351W. Our years came with Windsors vs the M's which were in the older trucks. 79 below I think. The 460 will also have a hubge head and huge exhaust manifolds.
Here is a pic of my 5.8 If it looks like this you got the 5.8L 351W

 

That's a screwy decoder, then. Position 8 in the VIN is the (original) engine, and yours is 'G', which is NOT the 351W (H). I think the G engine code is a 460.

Well, what you have pictured is a 351W not a 351M. I don't know about the VIN codes though. It was common to see the 351W in F250 trucks. I didn't know they put them in the F350 trucks. Come to think of it though I think Frederics truck is an F350 crew cab with a 351.

 

The VIN decoder is wrong.

1980/89 Ford Light Truck Parts Catalog sez:

G = 1980/85 = 351W 2V

G = 1987/89 = 460 EFI

Engine swapping: What engine izit?

460 = 7 valve cover bolts / 302/351W = 6 valve cover bolts / 351M/400 = 8 valve cover bolts.

btw: No 351M's (or 400's) were factory installed after 1982.

 

I've had the same issue with that decoder. It also says my 460 is a 351.


If it's an 88 it's EFI 460, that doesn't apply. The 460 has the tall snorkel intake with the horizontal throttle body.

 

wintremute is correct

 

maybe it don't matter ,but my 96 3/4 crew 460 looked jus like dat too. It had the 2 hoses coming from the middle too. my 93 351/w says 5.8 on top too.

 

Did ya fig it out? What engine you have. Also if you look at the tags on the rad support/hood it should say engine size. If they are still there. You should be able to tell if its a BB or a SB.

 

Thank you all for you replys. I've been busy with a death in the family and have not had a chance to reply before today. I used the FTE decoder, by the way, as well as the chiltons manual. I do believe this is a 460. This motor is strong. Thanks again for all the feedback.
