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.
do you think the lifter is operating like a hydraulic, or a solid?
more like a solid,but with dampening for the roller, no lash, so hopefully they will last longer on the street than all the horror stories of solids failing from street use, I said you can adjust them .020 from the bottom, mine are not done that way, mine are 1/2 turn from zero.
