1.5 vs 1.6 rockers

[leblanc]

I believe all stock 360's have 1.5 rockers. What effect will 1.6 rockers have?

They will make the cam seem bigger, will also give you less piston to valve clearance. Some motors respond from this, some guys will do either intake or exhaust. Best to ask a reputable engine builder.

Thank you

As Fisher said, it will make the cam a little bigger. You would see a difference in the lift but not really much, (not enough to make a difference), in the duration. By the time you change out the rockers I personally believe that you would be better off getting a cam that is bigger and made for your engine. That being said, it is a lot easier to change the rockers than a cam and you don't have to worry about breaking in a new cam.

Stock LA rockers are usually around 1.4 or so. 1.5 is the spec for a stock LA rocker and what cam makers use when they post lift.

I believe the stock 360 Magnum rockers are 1.6.

1.6 LA rockers seem to work well with ported heads that have good flow at high lifts.

They will add about .030 of lift, not really worth it on a stock engine.

I agree, especially if you have decent 1.5's on it already.

When I did my rockers it was a choice of 1.6 vs 1.5 for the same price.
So I went 1.6

The extra increase in rocker ratio will add a minor amount of intensity and lift to the cam. Figure approx. 2*'s more duration as I have been told. :dontknow:

To determine lift, lift is divided buy ratio times new ratio. Always check piston to valve clearance.

Same here.
Plus I can sound like a bigshot, when I say my cam has nearly 600 lift.
Plus every body knows that more ratio is the bees-knees, right?

Ok that sounded better in my head;.............heehee
