Cam manufacturer choice is mind boggling for me. i just stick with the Mopar stuff. You can do a post on the internet on any of there cams and find nothing but good things were people are happy with their grinds.
I have so tried to change but to what??? Hughes, Comp, Diamond, Racer brown , Isky , crowther,,,,ect Then all the specs seem to be a little different from manufacturer to manufacturer???
Then you have Roller- hyd or mech . You find people that say rollers fall apart on the street, The 440 doesnt have adequate oiling for any kind of idle situation. Hyd rollers float, mechanical's have to high a spring pressure for street
Mopar Muscle is always using rollers in there street builds but if you search you'll find people with roller assemblies that came apart and totalled there engine because of the pieces floating around.(alot of people say you need oil modifications to the heads of an RB and the same number say you don't)
i have used 8 purple sticks to date and never had a flat lobe but Im not an all out racer either and not the brightest with motors as of yet?
