valve size??
i need to know the sizes of my valves for my auto class and i cant find them anywhere. Does any one know the valve sizes for a stock 89 GTA? Also, does anyone know the fuel pressure and volume for the same car? any info will be greatly appreciated.

Im not sure of the valves, check the TPI or Tech/General Engine boards. As for the stock fuel pressure, its about 48 psi. Some say its not that high, but EVERY car I have tested has been at about 48, with the stock regulator. Injectors are 22 Lb/Hr.
Hope this helps.
