i am planning on swapping my current motor in my 78 f150 for a 460 how hard is this?which is the better 460 out of a car or out of a truck?im looking for the most horsepower and torque.would i have to chang out the tranny it has a np435 in it now with a np205 transfer case will this set up work of no?

 

If you have a 351 (or 400) in there currently, the 460 will bolt right to the tranny. I'm still learning stuff everyday, but my understanding is that the 460s used then are the same in the cars and truck (generally). Things like the pushrods might be heavier in the "heavy duty trucks, but it would still fit. Being on the green end of experience with this kind of stuff, I dont know too much more.

 

Is the truck a 4x4 or a 4x2? If it's a 4x2 then you can buy stock motor mounts but if its a 4x4 you need after market mounts.

The flywheel from your motor will not fit the 460. In 79 the 460 change the balacning of the motor from internal to external. The flywheel has to match this as well. In the late 80's the externaly balanced flywheel has 8 pressure plate bolts and the pressure plate you have will only have 6 bolts. Not sure if it has the extra holes for a 6 bolt. I have only read this and have not owned this flywheel yet. If you have a 78 or older motor a 390 flywheel will work and your pressure plate will bolt up just fine. I thnk the newer flywheel is taller and may hit your older bell housing on the inside. Again I have only read this.

The power steering brackets and all are different. You may have to get creative in order to make things work. Mainly the power steering.

If you have a 4x4 with no lift you will need a rear sump oil pan.

Car exhaust manifolds are different as well. They only have a 2.25 hole and the trucks have a 2.5. The car manifolr will hit the frame on the pass. side of the truck. The only option is to cut the frame or run the truck manifolds.

Thats about all I can think of for now.

 

Truck motors have a better crank,better rods,and the football headed(CJ style)rod bolts.Would imagine the cams are different too.Best 460(if you can find it)would be '69-'71.

 

I have always thought the cranks were the same. How can one tell if he has a truck crank over a car crank? Is there some kind of part number or something?

 

its a 4x4 long bed with a 302 in it now.9"rear.i was kind leaning towards an automatic with the 460. instead of a manual..its kind of a good thing my tranny wont work. it has a long throw 1st gear it touches the dash.and in reverse it goes way back..what would be the best automatic to bolt up to a 460?

 

the cranks are the same no difference, and only some of them had the "football" rods, not all.
for PS pump you can use one from a 2wd truck that will work just fine although you will have to get shorter hoses most likely.
exhaust manifolds, and oil pan form an E350 van will work for the 4x4 conversion, and if the truck origanally had a 400 with stock manifolds should even bolt right to the exhaust itself.
and personally the only auto I would mess with behind a 460 in your case would be the C6

 

Maybe so but we put a car motor in a truck and had to change the torque converter-where the pilot bearing would sit(in a manual)was different,the truck crank end was diferent size.Guess I should have said different instead of better.

 

I recall having a problem about 15 years ago wher I tried to install a 460 in my bronco which had a 4-speed trans and the pilot bearing stuck out of the back of the crank and would not let the bell bolt up to the block. We had to turn the pilot bearing down.
