Yeah after some thinking and research Ive decided to not put a 5.0L in it and put a 5.4 instead and use my 4.6 heads and buy an HPS intake and shorties. So anyways any suggestions?
well since you are going the 5.4 swap heres some good info.
first why do you want to swap heads?
Make sure the 5.4 is betewen 99 and 2004.
If you want to improve the 5.4 get a decent plenum and throtle body combo.
I,m using a ported accufab plenum with a 75mm accufab throtle body.
Remember that 5.4 love the extra air.
underdrive pulley will also helps.
what gear are you running right now?
