On the earlier 2.2L's (97 earlier) GM used a 1.5 rocker arms with a camshaft lift of .432 . When GM changed the 2.2 to the 2200 in 98, they started using a 1.6:1 ratio roller rocker arms with a camshaft lift of .420. To keep the valve lift the same they lessened the lobe lift on the cam. So in theory by doing the swap you will get a cam and rocker combination of .460 inch valve lift, instead of stock .420 lift.

What kinds of gains would this make on my car?

There is no secret

The timing on the two motors is different

So it WILL NOT work

Get a custom cam done

lowfire is right


it won't work so don't waste your time thinking about it
