MT/FZ 07 custom grind cam shafts
What you are purchasing is a regrind of your stock cam shafts by web cams. This is a custom grind made for me by web cam available exclusively through me. The will take your stock cams add material to them, regrind them to my specs, and then they are hard chromed for longevity
You can see from my dyno results below the gains are phenomenal with minimal loss in the lower rpm's.
I do recommend adding higher performance valve springs with these cams.
If not redline should remain stock to avoid piston to valve interference
After the cam install, you will have to readjust your valves , the base circle will change
These cams are designed to work with a full exhaust system, a HORD intake, and a Spears Racing .1 mm thick head gasket
