408 hyd roller, too much spring pressure?
I certainly wouldn’t be afraid to run beehives on a street strip deal. I did that very thing for the 4 years I raced( quite a bit) and street drove the motor below in a 71 Duster.
It saw 6400/6500 every pass it made.
Knowing nothing about beehives before this, I now know they are very capable to satisfy the needs of a great many, like myself, who race/ raced a piece at this level.
