I went with the Morel High rpm versions, $940.00 from Hughes, they work good so far, car ran 11.33 @ 121, 4100 lb Charger, no tuning yet, they are a little noisy when cold, you can adjust them .020 from bottoming out of the plunger, & they also recommend no heavier than 5-40 oil, I am running 10-40 Lucas racing oil with no problems. pulls great over 6200.
my car is a street car.
