what engine do you have,that we need to know ,if its a 318 you have to do a lot of work to it to get that much power from it,if its a 360 there's less work involved and a lot less money,you have to gut it though to get that kind of power from it,and completely go through it adding new pistons with head work as well as intake and carburetor changes on it,i got a 99 ram though with a 360 in it and it runs around 370 horse power,but it was built when i got it,the gas mileage is really bad on it though but it will literally burn the tires off of it when its in 4 wheel drive,you can also watch the gas hand move on it when you do this,but its a fun toy to play with ,good luck.
