i'm looking a getting a 1985 f150 supercab long bed 4x4, i was told it was a factory 460 truck but the 460 blew up, so they put a 351m(400) will the 460 bracket fit the 351m(400), and yes if i do get it i'll put a 460 back in.

 

What is the story here? They put the other engine in but left the power steering pump hanging off to the side?

 

Can't say for certain, its my dads buddies truck, i've only really looked at it once a i know it has the 351m, and that it used to have a 460, yes the power steering pump and bracket are just hanging over to the side, i was told he'd sell it for less than $1000, the body is in great shape low rust, cab mounts are good, floors are good.

 

i'm reading they never put the 460 in the F-150s might have been a factory 351M? they switched over to a 460 then put the a 351 back in, i know i need to look at it and talk to the guy, just trying to get some ideas.

 

351M/400 were only available until the 1983 model year, when the 460 came back.
There were no 335 series engines available or installed in 1985 model year trucks.

One easy way to tell if it was an original 460 truck is to use the eigth(?) digit of the VIN.
Another is to look for the oil filter clearance divot in the front crossmember.

 

it does have the divot in the cross member, i need to go look at it again, that guy works days i'm off and i work days hes off.

 

Well the timing case is completely different on a 335 series engine, so i doubt the power steering pump bracket can be made to fit.

The crankshaft also has different projection at the rear of the block so it is difficult to mate a 351M/400 to a 460 transmission even though the bell bolt pattern is the same.

 

351M/400: 1977/79 F100/350; 1978/82 Bronco; 1980/82 F150/350.

No 460's in F150's after 1979. 460 not available w/a M/T or 4WD until 1983.

1981 thru today: Engine code is the 8th digit of the VIN

1957/80: Engine code is the 4th digit of the VIN

 

So the bracket will not fit? Ill look at the vin first chance i get, it did for sure have a 460 in it( i agree not factory), and currently has a 351m(400) with the c6 that was behind the 460, i only looked at this truck once. Gonna try to this weekend some time.

 

If it has the oil filter dent in the crossmember the 460 was in there, because Windsor & I-6 trucks didnt have that.

I'd say someone swapped a 150 cab onto a 460 chassis, but then you would have eight lug hubs.

What kind of front axle and suspension does this truck have?

I wonder how well seated the torque converter is (given the different crank stickout (or if there is some kind of adapter in there)

 

He doesn't know anything. He said he glanced at the truck once. He is thinking he wants to buy it because it's cheap, but he doesn't know how much of a project he is getting into.

If you are not very mechanically inclined or know nothing about vehicles, a truck that has been seriously messed with like this one can be a very difficult school of hard knocks. I envision a lot of butt spliced wiring and a general mess. Be prepared for the worst if you buy it, I think the power steering bracket is going to be the least of your worries.

 

How come they never put the 460 in the F-150s?

 

Most but not all transmissions are smaller in the f150's, they won't hold up. The wheel bearings and suspension are smaller in the front, the 460 is heavy. I believe even the 9 inch Ford would have warranty issues stuck between a 460 and a heavy RV trailer going up a mountain or two.

 

Too much torque for the driveline​???
Yes probably way too much for an F150's 8.8 in stock form.

Actually, because emission requirements were more lax for vehicles over 8500# gvw.
So, no Cat.

 

That's probably the real reason instead of my post. They did put 460's in station wagons and they did pull some big trailers with those in the 70's.
