hi everyone

now this numbers are taken on a pull till 5600rbm , i have set my cut off to 6500rbm
i know i should at least be around 310+ hp 326tq , i have with me now a set of 799 heads and a NNBS intake , what is your recommendtion on this compo , how much to mill from heads , am i better off with another intake , i ordered nelson fan harness and soon it came it will be mounted with 05 oem e-fans

Port and mill the 799s. The NNBS intake and E-fans will make a huge difference. I would suggest a slightly smaller cam for a 5.3. Might not make as much peak HP, but it should make for more torque early in the powerband.
