i was just wondering if it is good to run 4.10 gears and a pi swap (just the intake manifold) my car kinda starts to get hot with 4.10's with alot of driving highway at high speeds i have been hearing that the pi swap helps in the high rpms and will that make my car run at higher rpms when i am just cruising or maybe do i need a lower thermostat plz help thanks

its going to help the car breath better. it would have less strain on the engine. what RPM are you at with 65mph? i can run 90 mph all day long and not get hot thats just under 2.9K

Intake manifold swap is good for like 15 I believe, but dont quote me on that... I have too many numbers going through my head right now.
I'm at work.
