Hey Frank. Do you want to be faster than the other cars.
The 3.23's are fine for most applictaions of a car to drive anywhere at anytime. The 3.55's are OK as well, but prefur a 3.23 for going far.
IMO, I'd leave the 1.88 valves. The 2.02's do not show well until later in the RPM band.
What other parts do you have for your cars engine?
