Stopping the knock: Lower compression and ported heads...

He did degree it. But from what I remember, he was not 100% sure where it ended up.

Along those lines, you need to remember, most cam manufacturers grind 4* INTO the camshaft. So, even if you install and degree it "straight up" it is likely advanced 4* already. SO, if you installed it advanced, you can probably add 4* to wherever you installed it, which would raise cylinder pressure even more. I am sure you can call Lunasty and they will tell you whether that particular cam is ground with advance or not. I bet a dollar it is.

It clearly says 106° ICL is 2° degrees advanced, not 4°. The IVO and IVC points at the 106° ICL are on the card. Don't add another 4° just because:banghead:
