Building a mean 460
My 91 F350's 460 is getting tired and I'm starting to plan to rebuild the hog. I want to get up into the 350 - 400 hp range and still have a reliable everyday motor that can fire up in all weather conditions, pull a 25,000 pound load and be an everyday driver. What do all of you know about products that I can use to build this engine? Any other websites I can look at? I would appreciate any of the advice you all can give me.
Thanks,
tb

I took a trip to strokerkits.com and ask a few questions about their 502 cubic inch kit. It's around $1900 and with some cylinder head work, a slight R.V. type cam, and no computer changes, they claim 450 to 500 pounds of torque and 400 to 420 total horsepower. Add in a Banks Power Pack, high flow cat, some ignition upgrades, and them horses in the trailer will need seat belts. For the money, it about the same as a remanufactured block with no modifications. Check it out for yourself.

I looked into this myself and found the best way to get up to the HP you want is to add a supercharger. I was quoted around $5.5K for the supercharger installed and adjusted. For cheaper gains you may want to try to open up the exaust some and add a ram airflow system, I have found the stock systems on the 460 to be a little restrictive.

Someday I'm looking into the possibility of rebuilding my dads 1990 460. Not looking for the cost and numbers listed here; but am thinking of milder mods.
Possibly: Sealed rings, higher compression ratio pistons. 3 angle valve job, port and polish and a RV cam.
Would these mods work with the stock computer?
Not trying to race it, but if I rebuild it then I'd like dad no notice extra power performance and maybe even a few extra MPG
