Re: high oil presure
Theres a difference between pressure and volume. All well and good to have loads of pressure but it useless without volume. It works the same way as fuel pumps.
I went and had a word with Chris @ Speedpro. He's been drag racing Clevelands for years. At 6500+ he recommends a high vol pump. Below that he say a standards fine. He said standards won't hold pressure @ 6500-7000rpm.
xdclevo : you sleeve lifter bores because the lifter bored needed machine due to being wide @ the bottom and narrower at the top. So with a high lift cam the lifter gets stuck and doesn't turn. Causing a lifter and cam damage. It's only common with high lift cams.
