Check my math, please-cam degreeing

I would shoot for around 104* mr gasket sells 2 and 4* keyways if the 4* is not enough. Sometimes you luck out and they are rite on. More often than not I have to tweek mine. 7* retarded and you would be looking at an extremely doggy 340. for what ever reason on my stroker was 116* straight up, 109* 4* advanced so i threw in a 2* keyway and got it dialed in @ 107* my cam has a 110 ICL wanted to be 108* but 107* is close enough for me
