1.steeda timing adjuster
2.drop in K&N
3. bullet intake if going with a vortech?
4.underdrive pullies
5.4.10's
I don't think the 4.10s are an over kill, on the way to the world ford challenge in st.lous we were tachin about 2,200 @75 I believe. Steve I thought the newer ones went with a 3550 or the 3650 tremec? Or was there a change over in 2000 to 2001. we went with a pro 5.0 after he had bent the forks on two transmissions. I would put that at the top of the list. Hey rara come up with anything on my combo?
