So I'm setting up my gt40p heads and I am deciding between 1.6 and 1.7 roller rockers.
I have an e303 cam which has a .498" lift. With the 1.7 rr's, lift will increase to .529". I also have the gt40 upper and lower intake with 65mm TB as well as 1 3/4" MAC Long tubes. I am also porting the heads as well as my upper and lower intake. I do not plan on shifting past 6000 rpm in fear of splitting my block.
Will my set up breath enough to make the 1.7 rr's worth the cost?
Ps. I am coming from the rotary engine world so I am still learning cam tech. Where does lift actually benefit the rpm band? Or is it better everywhere since it let's more air in?
