[Fot] Oil pump query

[Greg "Lunker" Hilyer]

Happy New Year all,
I've only used stock oil pumps in the past for the TR4, but recently  
came across something different. The outer rotor has machined  
"flutes" tapered to a depth of about .060". Although it came with a  
bunch of used parts, I think its NOS from about 30 years ago.
So... typical "hi-flow" that I would want to use? Or a cavitation  
prone idea that I should stay away from? Even if it's a common piece  
or something you've never seen either, any input would be appreciated.
Thanks in advance,
Greg "Lunker" Hilyer

Prepping for the Kas Cup at the Mitty - which leads to another  
question. Can anyone lead me to a good track map of Road Atlanta? The  
track's web site just shows a basic layout without distances or  
elevations. Is the back straight a up-hill pull? That might help. But  
it looks awfully long - as in my 4:10 gears [without overdrive] might  
be a bit short.
