Rocker Arms for 3400/3500

Just uploaded a video for the 3900 rocker using 3400 pedestal and its a no go.

I like the idea, but I agree, it's a total no go as is. I wonder if 3800 rockers would be a better match, assuming they are stronger.

I don't have any 3800 rockers to test. narrow body SBC are what we use. 4.3 roller tip is the right geometry, which it should because its a SBC with 2 cylinders chopped off (I hope, its what ive read).

there's a bit more to it than that, mainly some engines getting a balance shaft, but from a basic geometry standpoint, that is correct.
