Anyone run an F13 with big-ratio rockers???
Does anyone run bigger than 1.7 ratio rockers with an F13, or does that fall into the "why bother & you'll pound your springs to mush" category? Anyone got a cam card so I can calculate the ramp rate of the lobes? If so, what was PTV clearance like, and did you have to fly-cut the pistons?
