Tom(and everybody) As you might know gas is some close to $7 a gallon over here, so I kinda want to emphasize the mileage in whatever I decide to do. The 2.78 will stay, and I hope to be able to beef the low end torque as much as possible. No need for hard revving. My thought is this: Swapping the heads as is, get a new cam(067 or similar; is there a 066?) tinker with ign. curves and maybe jets/rods. How about advancing the cam? In theory it will bring up low end tq at the sacrifice of high end hp, which I really dont need?? Anybody with experience on this? Also, shouldn´t the intake valve size be good enough anyway as long as the rpm is kept down?
