highest rpm with 4gsk
this may be a dumb question and yes i know 4gsk is 4000 rpm but i have yet to put my 60 lb valve springs in yet so im careful about not going over 3200 rpm but it feels like it may be defueling before then. i can def get higher rpms then with the old stock ones but much over 3k now im not sure how much higher it will fuel to.

yeah im gonna have to go back through it im not really sure how how shell go cus i dont wanna go higher then 3200 until the 60 lb valve springs are in. i know i can def get to at least 3200 rpm but dang it sounds like it might not be able to fuel much harder. i just didnt know how high or rpms to expect from a 4gsk
