85 F250
New here; not sure if this is where you put this post, but I have a serious question. I have a 1985 f250. It had a 351w that blew up so I got a 460 big block. However, I am having a few malfunctions. My engine mounts off the 351 don't match up to put on the 460 and the 460 mounts won't work for the 351. And I can't switch the mounting plates themselves between the trucks. Anyone know what I can do or get to make this motor go into this truck appropriately?
Thanks.
Thanks.

Welcome to FTE.
If you do a search on 460 motor mounts or the like you should find something.
From what I have seen posted the frame mounts are different between the two motors. Even the six uses a different frame mounts.
IIRC one of the frame mounts or both are rivided in place. You have to remove the rivits to get the mounts out and use bolts on the new truck.
Also there is something about the front frame cross member for the 460 having a notch for the oil filter so check for that.

Thanks Dave. I have heard that people that do this usually get a fuel filter relocation kit. It would be nice if I could have just switched the front cross member out between the two trucks but the other is a bronco and it's longer than what I need.

I got to say I have not done any motor swaps only what I have seen posted.
Yes I think you are right on the filter relocation kit.
I hope what I posted on the frame mounts helps.
Can't sleep or at work? I am at work waiting for the guy I am training to show up. Can't remember if I told him 2am or 3am?

Just came in front the garage. Just pulled the motor. The f250 looks like it wasn't meant for a manual transmission and the one that just so happens to be connected to the 460 is a 4 speed manual. I have to find a clutch assembly for the pedals that will fit cause I can't the one in there to work. Plus I am at the moment running into problems with the rod that goes through the floor for the mechanical clutch. At the moment, where the frame is, the rod would either come up where the throttle pedal is or if you face it the other way, one the other side where my brake pedal is right now. Again in the wrong spot.

I sure when others get up they can help answer your questions.
What are the models, tranys and years of the 2 trucks?
Somewhere they switched to hydraulic clutch but my thinking is if you have a full setup you should be able to swap it as a whole.

The truck the 460 came from is a 1979 Bronco and the other is a 1985 f250 which I am putting it into. I have everything I need for a mechanical clutch already, it's just crossing everything over to the f250 where I am running into issues. Also I have limited funding so the go buy stuff option is nearly out for me. I can rig where the spring on the clutch goes and maybe the rod that goes through the floor board. I know I have to buy a plate for the clutch pedal mount and a relocation kit for my oil filter. And again the issue with the mounting brackets for the engine. Everything else beside fitting the motor into my current housing bay, I can account for.

Or, you can get the right perches from a truck with a 460 at the salvage, although it is a lot of work. Anyway, thoughts on swaps are here: Engine Swaps - ???Gary's Garagemahal.

460 not available with a M/T or 4WD until 1983.
You will need to determine if the 460 is internally or externally balanced.
Hydraulic clutch: 1983/97 F250/350 460 & Diesel / 1984/96 F150/350 & Bronco 300/302/351W / 1997 F250 H/D & F350 351W
1983/97 F250/350's used different 460 engine/trans mounting parts than 1973/79 F100/350 460.
460: 1968/78 Passenger Car & 1975/97 Econoline engine/trans mounting parts will not work on any year truck.
