1.6 or 1.7 Roller Rockers?????
 

Could someone please tell me the difference between the 1.6's and 1.7's. I mean with a stock motor and valve covers and all, would you have a problem using the higher or what. Basically what I am asking is, what should I get for a stock motor?:confused:

With a factory cam you will want to go with the 1.7's

Use the 1.6's with an aftermarket cam with the proper lift to match your combination.

1.6 or 1.7. That is the ratio that lobe lift of the cam is multiplied.

If you add 1.7's, you get a little more valve lift over the stock size of 1.6. As stated earlier, 1.7's are good for a stock cam, but if you are buying the cam and rockers together, get the 1.6's and the right cam for your combo.

the difference between 1.6 and 1.7 is exactly .30 thousands.

Go with 1.6's so you can build on them.
