Hello,
I need to know the correct rocker arm ratio for a 1990 2.5 liter TBI. The machinist who port/polished the intake/exhaust manifolds and head is working on a custom grind for the cam. I do not know the correct rocker arm ratio for the stock rockers.
I have read where they are claimed to be 1.55, 1.56, 1.7 and 1.76; I didn't think they would be more than mid 1.4's but then again, I don't know.
Also, if you know of a place to look, I am happy to do that but thus far my searches have proven inconclusive.

:facepalm:
