Lee- A six like small block does not need a damper to run because of netrual balance. I wont loose no sleep over it or burn up the phone line either. The Harrison's and Self are running dampers for a reason. My truck is street legal so I still have a altanator and crank trigger on it. A eletric water pump is the only way to go. There are plenty of things that rob horsepower besides crank deflection.
The water pump on the crank was not a smart ass remark it just most poeple wouldnt think of it being a damper. It you want it to be a smart ass answer well I guess it is.
Now on the oil pump thing I would have to check. I think a lot of companies claim high volume through higher pressures infact the gears are the same. I dont know it been a long time sence I messed with that sence I never have oiling problems.
