Pulley sizes

[unstable load]

Does anybody have the crank and water pump pulley sizes for the 3.5 engine to hand please?
Is the pump equal, underdriven or overdriven relative to the crankshaft?

Hi, Crank pulley is 6", water pump is 6¾". (P6b)

So, slightly underdriven.

This bloke's problem is that he has fitted a truck water pump with an adapter he made, and it runs close to 100C on the road.
On the track, it was fine due to the speeds he was doing, but now, he wants to go back on the road as a daily driver.....
