[Roadsters] Water Pump Pulley

[Howard @ Everything Christmas]

Thanks Steve,

Will look at that chev unit.

6.5 inches looks good.

The amount of power that your friend's engine is using and the length of 
events are also variables, I dont have problems at lower revs or on a Dyno.

Also thanks to all who answered direct to my email.

Best Regards,

Howard
