My little TR7 with a Buick V6 sheared the roll pin in the distributor gear last time at the track. This happened in the 4th round so the motor was not cold but after taking the oil pump apart today I found that the motor had a high volume (long gears) oil pump and I have been running 20w-50 motor oil in it. My question is does this motor really need the high volume pump as the car is only raced in the 1/8 mile classes and the RPM is not over 4700. The oil pressure at idle when warm was 40-50 and 60 (don't usually look going down the track) or so at RPM.
