Go to Fast man and get a set of PORTED heads and 206 cams. Then add a set of 4.56 gears, AIR RAM intake, ASP underdrive pulley, electric fan, High Flow muffler w/ electric cut out and you will be able to take most HEMI's for a fraction of the cost. And you will get better fuel economey.want2tow said:Hi,
I have a 03 Quad Cab 1500 4x4 tow package stick and a 4.7L motor. Can I swap my 4.7L with a 5.xL (anyway the new hemi) without many problems? Any ideas on where I can get the bigger motor?
