Rocker arm ratio

[Doug Brown]

What is the rocker arm ratio with solid lifter camshaft (88-89 Festiva) and the hydraulic lifter camshaft (90 --> Festiva / Aspire)? I think it is 1.6 to 1 (???????)

Does anyone actually have the specific camshaft specs of the FMS or Dickmeyer cam so I can compare them to the re-ground ones that I have found?

Or the part number of the FMS camshaft?

Thanks

Rocker ratio is 1.75:1 for carb rockers. Stock cam is .200" lift at the lobe, FMS (street/strip grind I think) is .254" lift at the lobe. So .350" stock and .444" at the valve for FMS. I don't have duration specs for either.

Thanks for the info. Do you happen to have the rocker arm ratio for the hydraulic lifter engines? (1990 --->)

One of the cams that the guy makes seems to have the same specs as the FMS street/strip cam.

That's the only info I have.
