When you order it tell them to cut it in. Most dont run the pump. Parsitic drag drains HP. They dont really do squat, if they did it would not have an oil slinger in them
My engine is a 33 and has oil pressure to both crank journals and the rod, so I figured I better keep it that way.
I love this forum, its a big help to everyone building mowers. I wish we had more time to post more. I just wanted to clarify a few things and give some of my opinions. We no longer grind our Cheetah profile for the single Briggs unless the customer asks for it specifically. We have been grinding our 440 profile for around 3 years because it makes more power. As far as Cast cam vs. Billet cam, I can tell you we have manufactured thousands of cast cams over the last 32 years with almost zero failures or problems. In most cases I can get the weight of the cast the same as the billet, in some cases I have got it much lighter. My cam grinder does not care, but I will say I have many more problems with Billet cams with lobe wear. Almost all Billet cams have a hard facing weld down the center of the lobe to prevent this. Almost all Billet cams will wear the lobes without the hard facing weld, which my not be visible with the eye.
Thanks for the info Mike.
