One thing to remember:
ANYTIME you change the rocker arm in any motor, you need to make
sure that
the valve springs are matched (Coil bind).
I contacted Crower for the 1.6:1 set for my 1997 V6 Dakota and they
stated
this:
"The 1.6 Rockers will work with the stock coils but you need to replace
the
Valve Springs when using the 1.7's."
The 1.6:1 set works great in my truck and the mid-range power has
definitely
increased.
