My Brenspeed cams finally arrived after being on back order for 3 weeks...Installed them in my garage. I had to buy the cam wedge tool for $75...I didn't use a spring compressor...and didn't use a torque wrench on the cam caps just by feel ...The install was very easy since I've done hundreds of cams,heads and motors when I was a Ford Engine repair tech...Well the rumble is awsome! Not one complaint about the cams. (Highly recommend Brenspeed).
