I change in my rebuild the cam , but not the springs, i'm almost sure that i'm going to have valve floating, but can this damage my engine?

 

more than likely the pistons will end up hitting the valves.

 

Too big of a cam and not having the right valvetrain to back it up can bend valves, bend pushrods, break springs, and cost a lot more money than just buying the right stuff in the first place.. But hey it's your car do what you want.

 

What cam and what springs do u have?

 

here is the cam specs, but i keep the stock rockers. I have the stock springs, I didn't change the springs because i,m waiting to buy a Trickflow assembled heads, i already check with trickflow and the springs are going to work fine for the cam, also in that time i will go 1.6rr.
Do you think that I can use the car on city (at low rpms)?
How am i going to know if valves are floating or not?

13 REMARKS

 

You won't experience any valve float at low rpm's if that's what you are asking.

You risk it when you are running higher rpms and the springs don't have enough pressure to hold the valves down after being launched off a larger lobe on the cam that is was designed to handle.
