The Crower kits come in either 1.6 or 1.7 ratio but are $1K and you still have to get studs and probably pushrods too. Not sure if those Crowers are for the Viper or truck engine and if there is a differance.

I have no idea if my rocker arm is 1.7 or 1.6 ratio. How would I find out? The pivot pedestal for the 01-03 engine with the 3/8 rocker arm bolts are also dc'd.
