I am reinstalling my cam in my 312 supercharged engine It is a Laneti cam. it has two key slots when I degree it one is at 92 the other is 112 nether seems right but it ran strong 13s. I called Laneti they found specks on this cam and they say it should be at 103 I did not build this engine I am just freshen it up. Anyone have any idea as to why it was 112?
