Any gains adding 1.6 rockers to stock 273?

Getting kind of late

The way I see it, the 1:6 ratio helps that. AND the ball to cup conversion on the adjuster.
Maybe. I think it's one of those things you just won't know until mock up. But, in the end, IMO it adds nothing at the rear tires, so what's the point? He could basically tight lash his factory solid lifter cam and almost mimic the results. But hey, what is it they say? "Not my monkeys, not my circus"
