Hi. How can I get more rpm’s out of my m670. Have zip tied the spring and it didn’t get me as many as I want. Thanks

I can get 2000 with zip tied spring I want 2400 or so

Oh ,cause NATPA will let you go 10 percent over factory for stocks .
Is it possible with those long rockers to go 2400 without valve float?
I do it with springs on smaller Farmalls on governors .
Mm guys will know what they are getting on that governor, if that’s possible.

I go 27 or 28 hundred somewhere in there on a bone stock 403 with no valve float. I’m way too far away from any natpa pulls

Just curios how you know that you have no valve float? Not saying you do just wondering how you know for sure? I would think a small amount of valve bouncing off seat when supposed to be closed would be real hard to detect??
