Speedmaster iron mag, 1.94/1.60 61cc
It took work to make them that way, but you can get there with stockers ported.
Stock cam isnt the limiting factor, the heads/springs and cyl pressure are.
Mill the heads to 60cc and you'll have enough dynamic for the cam you have.
Makes sense. The heads I have are stock but the aftermarket heads that are stronger. Maybe I will have more work done to them eventually. For now I'm gonna do headers and the 1.7 rockers. What is your tire size and gear ratio?
