460 rebuild
I have an f-250 with a 460. I was wondering how much it would cost to rebuild if I remove, disassemble, reassemble, and install it myself? Also what mods are a good idea(4 bolt mains, girdle, etc) for a future high hp engine?

Cost can run anything from a few hundred to $1000 plus. It's all going to depend on the amount of machine work needed on the items and the going rate in your area. As for the mods, more info needed.... what year 460? Carb or EFI? What is your definition of "High Horsepower"? To give you an idea... on the hi-power build I originally did for the 429 I put in my 90 F250, I was well over 10K in the build, and that was doing the teardown and rebuild myself. But it also included just about every upgrade goodie that could be done except EFI and a roller cam.

Bump... 1990 460 EFI... More curious about freshening up the stock motor. Nothing internal for now.

700-800hp is what I was thinking of. It's a 1991 fuel injected motor.
Not trying to be snarky or anything, but if you are asking cost and mods needed to hit that power range, you may be getting in a bit over your head. While the stock bottom end is good for 600+, and with mods is capable of way more than that, you are talking alot of work (and some serious $$$) to get into that power range.... headwork, compression mods, custom injection setup and ecm, etc all are going to be needed to do that kind of power. I'm not trying to talk you out of doing your own build or not build it up some, but suggesting being a bit more realistic in your goals. For starters, there is an excellent 460 section at FTE here---> Big Block V8 - 385 Series (6.1/370, 7.0/429, 7.5/460) - Ford Truck Enthusiasts Forums I would suggest starting by doing some research there and seeing what works, and what needs to be done to redo a 460. This is the build I did to push into the 650+hp range with a 429 in my 90 F250 a few years back....
Anytime you start breaking the 1hp to 1cube ratio it starts taking work. Even more so when you are talking a big block, and when you have a big block and are going for over 1.5hp to 1cube, well, as it says in my signature... |

For the best bang for your buck, do a stock rebuild, but port match the heads and intake manifold. Maybe look into larger exhaust ports more like the later 460 heads. Then add a pair of Tri-Y or longtube headers. While this is all pretty basic stuff, it'll offer you the biggest gains for the least amount of money.

I think an RV cam is good bang for the buck. Its pretty mild, but noticeable and won't wreck your mileage. That and a .030'' over job and headers are what I'm doing for my 94 F250 rebuild. Its mild, but its a little more.
