230/236 cam

I am putting a 230/236 cam in my 94 z28 and was wondering if the cam swap would call for upgraded valve springs or would the stock valve springs do? Thanks!

Do not try to run stock valve springs with that cam!
Your going to do some engine damage if you do!

Op

These would be a good spring for your cam, Lunati. You need new springs for any cam you go with

I think you need to research your cam swap more if you weren't sure if you should replace valve springs.

Listen to Ed. My engine builder considers him the ultimate authority of all things related to Gen II LT1's.
