Now i want to do the intake cause im gettinb the air out good now i have to get more in and i should see an even better gain. Is it possible for me to put a 5.8 v8 in my truck? its a 92 f 150 xlt. That would be nice if i can cause i can get the motor for next to nothing probably from a friend that owns a salvage yard.
Anything's possible if you put your time and money into it. Going to a 5.8L would involve a lot of changes, from engine mounts, to changing out the transmission so it can handle the higher output, to retuning the front suspension to handle the additional weight.
As for the throttle body, it should fit without much hassle depending on the year. I know for some I6 engines, they had dual inlets like the older Dodge trucks, but later switched to a single 70+mm opening.
If you want PERFORMANCE without spending a lot of money, your best bet is to swap out the gear axle, or just the gears, for a lower ratio. If you're running say 3.55s, going to 4.56 ratio will give you the performance of a lightly modded V8. The downside is increased mileage (slightly) on the highway, but again, a V8 eats gas just as well anyway. As you'd be willing to swap it out for a 5.8L V8, I can't see fuel cost being an issue. A rear end swap can be done for as little as $200 if you do the work yourself. If you want taller gears, like 4.56 you'll have to order them, as a salvage yard won't have those in stock. New gears will cost a few hundred dollars, installation will double the price.
