Engine ?
 

Heres my question. I bought a 89 Daytona, not sure if it just plain or ES. replacing engine. It has the 2.5L non-turbo one and I keep hearing about these balancing shafts and disconnecting them for more hp on the engine. How does that work, so I can do it before puttin the new engine in. Can anyone help?

If you remove the oil pan, you will see the balance shaft assembly and the chain that drives it. Removing the balance shafts frees up some horsepower.

Thanks roadrunner, it is a new long block that I have comming and I have to install the oil pan back onit so figured I would do it while it was off. Do you know if it causes any problems disconnected and thanks again

Removing the Balance shafts do free up some power. DO NOT forget to to plug the oil feed gally to the balance shaft assy or you will have 0 oild pressure and could possably wreck the top end before you can say "where is the oil pressure"

It will also help by getting rid of a few pounds as well.
