Setting base timing for performance cam

[Fast355]

You sure? Are you super rich? Something is wrong? 50* is nitro top fuel timing and their spark plugs melt before the end of 1/4 mile but magneto will spark to anything at that point...

I am going to say his dampner has either slipped or he has the wrong one for his timing cover.

My damper has not slipped. I used a piston stop to degree it. The timing marks line up correctly.
