Tech - Thanks for the explanation. I've had people tell me not to use high volume pumps for street engines in the past, but nobody could ever explain why. I always got an answer like "It's bad for the motor." Huh? Anyway, I never considered the drag on the distributor gear and timing set... I know where all the pieces go and how to use a torque wrench, so I assemble my own engines, but I'm not really an "engine man" and my engines are always pretty mild-mannered. I rely on the guys at the machine shop, what I read, and what little I've learned over the years.
