460- Supercharger or Turbo?
Ive been building a 460 for my F250 CS SC. I took a bone stock 460 to a local machine shop(bad idea) and he did a great job on the machine work, but for some stupid reason I let him talk me into him ordering a master parts kit for it. Composed of pistons, cam, etc. Well It was not supposed to be stock, or even close to it, but that what i got. Didnt end up finding out till after I got it back(not assembled) he didnt provide me with any specs, just told me that its got an rv cam. He tells me this after I Paid him $1900.00. So basically im stuck with it.
so I have been doing research on putting either a supercharger on it or a turbo set up. At this point money is tight, so I have 3 options redo everything, Supercharge it, or turbo it.
Just looking for some input on what you guys think. IM NOT GOING TO BE CHEAP WITH THE REST OF THI MOTOR> BUT DONT WANT TO WASTE MONEY>

i've never had any experience with a turbo before but am eager to learn. Is a lot of knowledge needed or is it simply a bolt on? and what size intercooler? noticed several different sizes. I'm reading all i can on turbos but hands on experience info i feel is easier to understand. and i've built engines before but want something different in my truck. and i've never seen one on my truck before that or a supercharger,
thanks for the info so far

I have built several turbo cars but never with a carb motor. To assemble a turbo kit would be a good deal of money. My suggestion would be to get the motor together as I suggested earlyer and then start colecting the parts to assemble a kit. The best affordable turbo would be one off of a late 90s to now duramax. It's not Garret but it's a feat turbo meant to last for years. It's specked for a smaller motor so it would spool up rather quick. You would only need about 4-5psi or you wouldn't be able to keep your drivetrain together.
The low end ***** of a 460 backed by a turbo would be sick but almost totaly impractical. But after all... It's smiles per gallon in out trucks not miles per gallon

Well nothing ix in stone yet but Im still planning on continuing the motor as is, naturally i cant afford to buy a turbo set up at once anyways so itll be down the road. You say collect parts for a duramax, Whats the difference other than $ between a turbo off a duramax and a TO3 as Ford six mentioned? And Ive heard different controversies between using twin setups compared to singles. IN your guys opinion what would be better?
Thanks guys all the info is helping!
That video was awesome. Thats what im looking to do, Want a little cleaner setup but thats it.

the economy is very uncertain. and if money is tight you do not need to be dumping it into turbochargers. if you already have a strong and almost new 460, then that is better than what most people have, (a tired 360) and that is plenty of power. if you really must blow your money, then like dude said you can put headers, ignition, carb, cam, and all that stuff and get a little more power out of it. there is no replacement for displacement, and besides, dont turbos force more air and fuel into your engine thus making it wear out faster?

I installed a Mustang fuel tank behind the rear axle on my truck and relocated the battery to get some weight to the rear. The tank, full of gas adds about 140 lbs. to the rear end. My 466" naturally aspirated motor barks the tires shifting into 3rd gear at 80+ mph. If I mash the gas at any speed where it drops back down into 1st gear, the truck goes sideways. If there are any bumps in the road on a full-throttle 3-2 downshift it will break the tires loose and I have to lift.
With a twin-turbo set up you are going to have to put a lot of money into the rear suspension to get the power to the ground.

Agreed!! A stout 460 is a great powerplant.
Twin vs single turbo is the same argument as what size carb. Ultimatly it's what your motor can use And what your building it for is what's best. A mostly stock motor would be safe with a single Werner Ishi turbo off the duramax. It can flow more exaust than the standard Garret T3 so it wouldn't "stack" exaust gasses befor the turbo.
If you ran twin turbo I would go with the T3 because of it's smaller exaust side. Only flowing half the engine each it would flow fine and still spool pretty fast. Not as fast as the single Werner Ishi but it would make more top end seeing how 2 turbos create twice the cfm. It gets complicated beyond this point!! I'm going to give myself a headache if I start breaking out the pulse width and boost curve crap!!

If it seems too good to be true, it probably is. There are no manifolds, you're on your own for those. Shipping is $80. Lots of common words misspelled, along with poor grammar, plus those are a bit big and would give horrible lag.
