If the battery is ok - the starter might need some shimms..
Easy enough.. Pop off the starter - put a few shimms in whre it bolts on..

Will a f350 with a 460 ci transmission fit in a 95 f150 with a 351ci

I guess the short answer is I doubt it.
The 460 engine should be a big block and the 351 is probably a large 302. I would expect the bolt pattern for the bell housing to be different along with the mounting and the tail shaft.
The 460 should have a bigger drive shaft than the 351.
If you can get the model of the 460 trans a salvage yard should be able to tell you if they will interchange.

1998 F150 Hard to start when hot. Have to crank engine for 30 seconds. Runs ok after starting. Check engine says it is running lean. Starts ok when cold.

I have the same problem with my F150 4.6. Long cranking when out door tempurature is hot. Engine temp gauge indicates normal engine tempurature. Looking for solution.

My dad's 1986 Ford F250 pickup, 460 CI won't start, no lights,

It could only be a couple of things. First check the wires to the starter solenoid. There will be a positive cable from the battery to the relay. Then you will have two more wires that go to two terminals. Jump between the positive terminal and the starter terminal. It should crank over. Sounds like you already did this step. If it does not crank check your battery. If the battery is good and you have power to the relay then I would suspect the starter bendix is probably to blame. You can replace the bendix on the starter. If you still have no power you will need to start at the ignition switch. Hope this helps. Also the gas in the vehicles tank could be bad and causing it to not continue running. Sitting for a year with a fuel tank not full will allow condensation to occur in the fuel tank. Last but not least most fusible links are attached at the starter relay because this is where the main power distribution occures to the vehicles other systems

My 86 f250 460 engine has hard time starting; New fuel filter, rebuilt carb, new plugs, new dist cap and rotor... i have to pump a few times, crank,,,, pump some more and then crank again for it to start

Check the choke in the carb, might stay stuck in the open position when engine cools down. After the engine is cold, check and see if the choke is closed, if not close it by hand, and see if that works.

My 1999 f150 wont start

Go back to your battery connections and make sure they are clean. If you recently replaced terminal ends, pull on the wires and see if it cranks.

Truck cuts off while driving down the road.

Replace the TFI module. Ford back in 1986 thur 1993 had problems like the one you wrote about. TFI module gets hot and shuts car or truck off then when it cools sometmies starts and sometimes not.

460 hard cranking after warm

First thing you should do it take it to a Ford dealership and tell them of your lack of power concern. They have been known to have fuel pump problems, low fuel presure causing lack of power. There may be an extended coverage recall on your vehicle that you cover the replacement of the fuel pump.
