Youtube videos dyno 318 magnum stock vs cam upgrade

Another plus for a roller- zero brake in issues, and can re-use the lifters.
especially with cam failures going crazy with FT. So many competent builders are loosing flat tappets anymore it's stupid crazy. I have to believe it's a Quality thing. I'm pushing more towards rollers in my future with small blocks. Pretty easy to get a roller motor - Magnums and later LA's. Just makes sense.
