Enough power????

I have a 1990 f-150 with a straight 6 4.9L in it. i was just wondering if there was enough power in there to be able to put a 4 inch lift on it and proably 34s or 35s adn them being like 12.5 wide.
Thanks

To complete your answer, yes it will have more than enough power. But, running 35s you might need to re-gear. When you lift a vehicle, the original factory gears are tunned to run no bigger than a 32 inch tall tire, you will loose power when you step up to a larger tire. So i would suggest 4.11:1 gears instead of the original 3.73:1 (I think).
