opinion comp magnum roller.

Lift seems "reasonable",and you know your stuff(by reading past posts).... I ran a [email protected] hyd. flat tappet came,in a 10:1 408.Agrressive,YES. Unstreetable,depends on you... Knowing gears out back, would help immensely. I would consider. 575 lift on a solid roller,mellow. I have seen bigger,live on the street(limited use,and maintenance!!!).
