Default 1.7 vs 1.8

All of the listed cam lift values are based on the stock 1.7 rocker ratio.

Just take .590 and divide it by 1.7 = .347 is the acutal lift of the cam lobe.

Now take that times 1.8 = .624 That's your total lift with 1.8 rockers.

Are there provisions on the side so you can slide the cam out, or will you have to drop the cradle and lower the engine?

I'm a little confused if I were to divide .590 by 1.8 I get 3.27 and can u explain the numbers cause if u do it for the 1.7 shouldn't u do it for 1.8 seperatly instead of adding them up? And yea I gotta drop the cradle and lower the engine . Drive belt is on the passenger side

use the stock rocker arms, go to compcam website and find a cam that fits your needs.I like this cam,54-408-11. Or check out engine power systems cams.
