302 to 460
My 302 in my 85 f-250 4x4 is just to weak. I think its time to graduate to a 460. What i,m wondering is what year 460 should i look for for this project. Also what differences ,if any, is there between a 460 from a truck vs. a car. What obstacles should I expect to encounter during this project. I should mention that the truck came factory with the 6.9.

You have a lot of work ahead of you. I just about have the bugs out of my 351W to 460 swap. If it is a manual you will need a different bellhousing and flywheel. If it is an automatic you will need a different tranny since you can not change the bellhousings. 302, 300-6, and 351W have the same bellhousing pattern. You will need to find a factory oil filter relocator or by an aftermarket one($300 from L&L). I had to replace the mounts on the frame, one side is riveted, I bought both through the dealer. This is about all I can think of at the moment.
Good luck,

[updated:LAST EDITED ON 05-Dec-01 AT 00:26 AM (EST)]I guess i should have mentioned that the truck came original with the 6.9 diesel. when it threw a rod I replaced it with the 302. I also had to change the frame mounts to acommadate the small block. then I had to cut a hole in the cross member for the oil filter on the 302. I do still have the 6.9 bellhousing, are they the same as the 460? I also still have the big block frame mounts, so that part is covered.

I believe that the 460 and the 6.9 require different bellhousings and also different frame mounts. Could be wrong, but that is my understanding. Also, I know that the newer trucks have a different radiator for the 460 than for the powerstroke.

You never mentioned what you had for a Rear End.
I suggest an early 460 or late 429.
Things you need:
429/460 Motor Mounts for truck
429/460 Torque convertor for a C6
C6 from a 400,429,460
Oil Pan for Truck
Drive shaft for C6
I suggest getting the Whole Donor truck for the swap.
It is usually more cost efficient to go this route.
Plus,you will have parts to sell to help pay for the swap.

I,m pretty sure the rear end is a ford 10.25. the tag says 3:55 open diff. As for the radiator, i still have the 6.9 radiator in it hooked up to the 302. i was a little concerned about it running to cool at first, but the temp guage stays 170 to 180.

Do you have your heart set on a 460? I agree, when I had the original 302 in my f150, it's just too small. I always had to use low range on the transfer case to do any serious pulling. Why I made the first statement is, I installed a 351w and am much happier with it. And it is a much easier swap as everything bolts up. You just have to change the oil pan and the exhaust y-pipe plus a couple of minor little things.

I thought about a 351W but wasn't sure it would have that much more torque than the 302. never owned a truck with a windsor before. What kind of difference is there in the ratings of the two.

I have got to agree with franklin2 on this. You should consider a 351W or a stroker based on the 351W. It would enable you to keep your current tranny/bellhousing, engine mounts, and possibly even your accessories. A 393 should put out an easy 400 ft/lb torque. You need to do some research to see which would be the most economical for your particular situation. But if you do have your heart set on a 460, by all means go for it!!!
